"Sophia... Please guide me... I will destroy all false pretenses of love, for you...

Karellen (カレルレン, kareruren), known as Krelian in the English localization, is a major antagonist in Xenogears, ruling along the likes of Cain over the nation of Solaris.

Using the power of science and technology, such as nanomachines, Karellen retains the appearance and health of a young man, but speaks and acts like a man wise beyond his years.


Karellen is a man of contradictions. He commits horrible atrocities and suffering on a global scale, which he deems "sins" which he knows are morally questionable, such as biological experimentation, like Mugwort and Rattan.

A sensitive man that tries to suppress his emotions, Karellen ends up having a difficult time doing that, ultimately having to face the guilt and responsibility of what he has done. He has an unnatural wisdom, built over the course of over 500 years, resulting in a rather jaded, disturbed outlook on life.

Karellen's actions are the result of the sorrow of having lost his unrequited love Sophia, his resentment at those who caused her death, and his lost hope and love for humanity. After Sophia's death, Karellen underwent a drastic change in mentality, going from a gentle and benevolent man into a hardened misanthropic scientist, burdened with despair as he searches for real deity to save human beings from themselves.

One constant characteristic of Karellen is that he always thinks of himself as a man and agent of "God", although he entertained this notion of "God" in different ways. Karellen's original goal, Project Noah, was to "resurrect god" (initially, Deus), or to create a deity of his own. At some point in time, Karellen analyzed Razael's Tree in Mahanon and learned the truth of Deus' dark nature, as well as the Wave Existence. Karellen's goal then shifted into "go to the place of god" and reunite with the Wave Existence. Karellen still intended to revive Deus, but only because Deus's resurrection is necessary for the Wave Existence to return to its higher dimension, and by extension, all of humanity and all life would return to waves and be one with the Wave Existence in this higher dimension.

This is how Karellen plans to "save" humanity -- by erasing humanity altogether into a form of non-existence.


Blue-haired Karellen as the leader of the Nimrod-Nisan army.

Karellen was born in the year 9465 in the country of Nimrod, which at that time was the largest country on the surface outside of Shevat. His mother Elazaru died of an unknown cause - possibly illness. As a young man, Karellen joined Nimrod's military.

At the age of 23 in 9488, Karellen was sent to kill Sophia by the Emperor of Nimrod, Kusel Laodicia. However, he found himself unable to do the task. Instead, Karellen befriended the 13 year old Sophia, and helped her recover since she suffered from a congenital illness. He eventually and gradually fell in love with Sophia (despite the 10 year age gap) and ran away with Sophia for 7 years.

In 9493, on a trip visiting away from home, Lacan was pulled into the conflict over rule with Solaris and there, he met Karellen. Lacan mistakenly thought Karellen and Sophia were together and so Lacan and Sophia don't fully reunite.

In 9495, Karellen and Sophia returned to Nisan and he joined the Nisan military. Soon, Lacan and Sophia became reacquainted. Both Lacan and Karellen loved Sophia, but Sophia seemed to have more feelings towards Lacan (naturally, given the relationship between the Antitype and Contact), which angered Karellen.

At some point in time, Karellen was studying under Taura Melchior, his teacher. Karellen borrowed a book from Melchior about a form of molecular engineering found in the ancient ruins of the Zeboim civilization. It was a copy of Kim Kasim's research report, but it was incomplete. Karellen developed an interest in nanotechnology.


Xenogears - 42 - The Story of 500 Years Ago, Part Three

Sophia dies as she rams the Excalibur into the Merkava.

In 9496, the Shevat-Solaris War between Solaris and the Lambs began. Karellen was part of the Anti-Solaris Alliance.

Karellen vows to create God.

At the end of the war in 9500, Sophia sacrificed herself while helping clear a route for allies to escape. Her death devastated Karellen. In his grief, while questioning the existence of God, he remembers Sophia's words--that faith in God should not be sought externally, but rather that it comes from within. Misunderstanding her meaning, he resolves that if God does not exist, he would create Him with his own hands--an effort he would come to call Project Noah.

In 9501, the Diabolos Collapse occurred due to Lacan becoming Grahf, wiping out almost all of humanity. The loss of his friend devastated Karellen and strengthened his resolve to fulfill Project Noah.

At an unknown point in time, Karellen met Myyah Hawwa, and she told him about the truth of the many mysteries of the world. She told him about Deus, and he agreed to join her side in their mission to revive Deus.

In 9506, Karellen met Cain, the Emperor of Solaris. Due to Karellen's knowledge of nanotechnology, which he had learned from the Shevat sage Melchior, Karellen made himself quite useful to the Emperor, although Cain would eventually be a hindrance in Karellen's mission and Karellen would desire to assassinate Cain. Later that year, Karellen successfully revived eight of the Gazel Ministers as computer data in the SOL-9000. Due to his vast knowledge and skills, Karellen quickly became the most powerful and important person in Solaris, even more so than the Emperor and Gazel Ministry. While they were to the public, the ones in charge, Karellen had become the true leader of Solaris.

A few years after meeting Cain, in 9511, Karellen, using nanotechnology, was able to permanently extend the life of not only himself, but also Queen Zephyr and the three Shevat sages: Gaspar Uzuki, Taura Melchior and Isaac Balthasar. Karellen did this to them as punishment for Shevat allowing Sophia to be killed, and so that he would be alive because he realized Deus' resurrection would not occur for several hundred more years.

In 9698, Karellen forcibly put genetic Limiters into all the Lambs to prevent any future uprising. How this was accomplished is unknown, but it could have been done by the Limiters in the food and medicine in the Soylent System being fed to the populace.

In 9959, Karellen initiated the fifth stage of the Malakh Plan. He came into contact with Myyah's 996th incarnation.

Karellen and Myyah (Karen) creating Ramsus.

In 9975, unable to locate the current incarnation of the Contact, Myyah cooperated with Karellen to clone an artificial Contact of Emperor Cain using Emperor Cain's DNA: Ramsus.

In 9985, Myyah possessed Karen Wong, Fei's mother, and alerted Karellen of the new Contact's existence. With the original Contact now in their hands, there was no need for a clone, and so, Karellen and Myyah trashed the 10 year old Ramsus.

In 9991, Karellen plans the third invasion of Shevat.


Karellen's ship, the Ezekiel.

The first mention of Karellen is by a member of the Gazel Ministry, who says that Karellen is going to Aquvy in order to intercept a ship (the Thames) that has discovered the ruins of Zeboim. Within Zeboim lies Emeralda Kasim, the quintessential nanomachine creation. The Gazel Ministry, however, considers Karellen's search for Emeralda "exorbitant." Soon afterward, Karellen makes his first appearance in the game, aboard the Solaris ship Ezekiel. Karellen orders his test subjects, the Wels, to attack the Thames.

Later, some of the game's heroes arrive in Zeboim and discover Emeralda, but Bishop Stone arrives on behalf of Karellen. Stone claims, "if Karellen uses the nanomachine colony, at least we can save some chosen people." Stone proceeds to escape with Emeralda. Karellen is later seen reporting to the Gazel Ministry that he has obtained Emeralda; Karellen also reminds them that he revived them and will not take orders from them. In a later meeting with the Gazel, Karellen announces that he has gathered all the data that he needs from Emeralda, and so he does not care what happens to it.

Karellen is next seen using one of his clones of Emperor Cain, whom Karellen has kept alive via nanotechnology, in order to speak to the people of Solaris. At this point, Elehayym Van Houten reveals a key plot point to Fei Fong Wong: Karellen is the real leader of Solaris. Fei suddenly blacks out and remembers his previous incarnation, Lacan, speaking with Karellen in Nisan 500 years ago. Karellen begins mentioning something about saving people's lives, especially Sophia's, but at that point Fei awakens.

"Elehayym, you are beautiful. When I look at you, I appreciate the artistic aspect of the human form, its elaborateness... I can't help but feel the importance of that. As if my molecular machine is unworthy of you."

Fei and Elly enter Karellen's laboratory in an effort to rescue the rest of their party, but Karellen captures them as well. Karellen discovers that Elly has the 'Urobolus Ring' and is the 'Mother.' He also calls Elly "beautiful" and says that she has not changed "since then." After Karellen exits, however, Citan Uzuki helps the party, including Elly, escape.

Back on the Ezekiel, Karellen again speaks with the Gazel Ministry. He says that he has sent Ramsus to handle Fei. When a Minister questions Karellen about his amicable past with Fei (Lacan), Karellen responds, "I've thrown away all feelings of human emotion. All I need is her." Karellen then contacts Ramsus and tells him to retrieve Elly, but Ramsus ignores these orders, since he is only concerned with defeating Fei.

Karellen appears in another discussion with the Gazel Ministry. Here he reinforces the importance of Elly to him, but also says that since he can get her any time, it does not have to be now.

Presumably, this delay is because of Karellen's conspiracy against Cain. The Gazel Ministry states that Cain "dares to go against our objectives." After the Ministry harasses Ramsus by calling him "worthless," Karellen initiates his plan. He tells Ramsus—Karellen's creation who is able to kill Cain—that Cain's existence divides Ramsus' power. Ramsus, desperate for more power in order to defeat Fei, complies with Karellen's orders. In a key statement, Karellen tells Cain, "I try to lead the people 'in my own way.'" Ramsus then successfully assassinates Cain.

Karellen decides to crucify everyone - even Chu-Chu and the Gears.

After Cain's death, the Gazel Ministry uses the Gaetia Key in order to make Mahanon rise from under the sea. In Mahanon, Fei and his party discover Razael's Tree, but Karellen appears and takes it, along with Deus. With Grahf's help, Karellen captures the party; Karellen needs them as bait in order to lure Elly to him. Karellen takes the party to Golgoda and crucifies them.

Elly goes alone to Golgoda. Karellen offers to let the rest of the party live if Elly can defeat two Gears. She does so, and Karellen keeps his promise. Karellen then returns to the Ezekiel after announcing that he is going to take Elly with him.

On the Ezekiel, Karellen meets once more with the Gazel Ministry. At this point, Karellen betrays them, claiming that since they have activated the Gaetia Key, he no longer needs them. While he is erasing them, he strongly rejects their claim that they could have become god; Karellen says that humans can only entrust themselves to god.

Karellen then constructs the Ark of Merkava by using his knowledge of nanotechnology and Razael's Tree. Karellen takes Deus and Elly with him to Merkava. While Fei and the party attempt to rescue Elly in Merkava, they meet up with Ramsus. At this point, a flashback shows that Karellen created Ramsus as an artificial Contact, but discarded him after learning from Myyah Hawwa that the true Contact, Fei, was born.

Ramsus attempts to kill Myyah and Karellen.

In front of Deus's massive form, the party finds Karellen and Myyah waiting for them, as well as an unconscious Elly, bound on a cross. Karellan explains that Elly, as the Mother, must be sacrificed in order to revive Deus.

Ramsus then appears, questioning his purpose in life, and is taunted by Myyah and Karellen. Ramsus, realizing he had been used, kills her and Karellen. As she collapses, Myyah remarks that, as someone fated to be unable to kill herself, this was the only way she could die. Meanwhile, due to Karellen 's body being mostly composed of nanomachines, he quickly revives.

As Fei frees Elly, he is suddenly shot. As Fei slumps back against Citan, it is revealed that Elly shot Fei, using Billy's gun. As her hair color, facial expression, and speech change, the party realizes that Elly has turned into the next incarnation of Myyah. After revealing the truth about Deus's nature and its coming plans for humanity, the 'Last Myyah' leaves with Karellen and is reabsorbed into Deus, in order to serve as the main protocol to Kadomony.[1]. The party is forced to retreat as Merkava raises into the sky, firing a red beam of destruction on the land below.

Eventually Fei's party manages to destroy Merkava, but Deus's completed form emerges from it. After a long battle in Deus's core, Fei's party defeats Deus.

Searching for signs of Elly, the party discovers a slight energy response within the core, which started to strengthen. The Wave Existence, which was used to power the very biological computers that led to Myyah and Elehaym, was finally freed from its "cage of fleshly existence" from within Zohar. It meant to travel to the higher dimensional it originally came from, which, as Citan revealed would create enough energy to destroy the planet. Elly, now free of Deus's control and in its the body, is trying move it beyond the atmosphere, intending to sacrifice herself one last time.

Fei gives pursuit in the Xenogears, the only Gear left operational after the destruction of the Zohar Modifier, disappearing into the rift.

Inside, Karellen confronts Fei, asking why he is so attached to all the imperfections of human existence that he would prefer it over reverting everything back to when it all began, when all was one in the realm of God.[2] Because humans live in an imperfect state that is filled with sadness, Karellen wants to revert everything to the perfect, unified state of waves, filled with the love of god instead of the false love that humans experience.


Final Boss Urobolus - Xenogears

Karellen pits Fei in Xenogears against Urobolus.

Fei rejects Karellen's ideology, stating that humanity's imperfections meant they had to help each other in order to live, which led to mutual understanding. Perfection is not needed for love to exist, and Fei understands this through Elly and her actions. He argues that Elly is trying to heal Karellen's heart, and that Karellen doesn't need to "become one with god" in order to understand her love.

Karellen challenges Fei, telling him to prove this love that could make him independent of God, and calls forth Urobolus, a gigantic serpent-like being, bearing the last visage of Myyah. Xenogears appears, and Fei phases into it, using it to defeat Urobolus.

After Fei defeats Urobolus, Elly appears. Elly reveals that Karellen released her, and tells Fei that Karellen was deeply saddened by Sophia's death and loved humanity greatly, and so he tried to make it so that no one would experience loss again.[3]


I envy you two

Karellen moves on to "walk with God".

Karellen appears again after Fei almost sacrifices himself to save Elly in the dimensional rift. Karellen says that now that there is no more god, this is now their planet. He then reveals that won't he be returning as he can no longer live as an ordinary human after everything he has done. Fei begs for Karellen to reconsider, but Karellen smiles sadly and solemnly replies that he has chosen to "walk with god" by following the Wave Existence back to its higher dimension, via the Path of Sephirot.

Karellen turns away and weeps, accepting the possibility of non-existence and he will never return or see Fei and Elly again. Two glowing wings bloom on his shoulders and he says, "Actually, I envy you two," as he disappears.

After the end of the credits, a golden feather is seen falling over the Kadomony's stasis pod, echoing the feathers that sprouted from Karellen's back.


  • "Even so, there was a time when I did some pretty vicious things... I lashed out at random... Everyone around me feared me... Even my friends. I lived a life surrounded by people who looked at me with fear in their eyes. But she was the only one who wasn't afraid of me. She would just smile. Peace of mind... She was the one who taught me what that was and how I could receive it... She taught me how to live as a human..." (in a flashback)
  • "We were sacrificed as pawns... In order to protect their own authority... Sophia was... Is this the ideal world we've been searching for? What have we been doing? Heading toward Sophia's ideals? Is this our salvation? This isn't fair... Sophia was sacrificed... for those bastards... Sophia said, if you just have faith the path to what you hope for will open." (in a flashback)
  • "What may be an eternity to man is a moment for god. I have no need for hesitation."
  • "I see... So you've seen the research facility. Presently, the Solaris researchers are working on genetic engineering down there. It's just a nest for fools who've learned the despicable pleasure of... ...playing with their own organic creations. They seek only serendipity and inhumanity. That is not my place. I specialize in molecular engineering... Nanotechnology."
  • "Elehayym, you are beautiful. When I look at you, I appreciate the artistic aspect of the human form, its elaborateness... I can't help but feel the importance of that. As if my molecular machine is unworthy of you. You haven't changed 'since then'. Just like the 'other one', Lacan..."
  • "I've thrown away all feelings of human emotion. All I need is her."
  • "God? Who said you'd be God? What impertinence! We are humans. We were created to be terminal interfaces of God. It is the same for you, who were once humans. Man cannot become God. We can only entrust ourselves to God." (to Gazel Ministry)
  • "Yes. It is indeed time for the resurrection of god."
  • "Lacan... Why such reluctance to become one with the god? What attachment could you possibly have to this wretched old world? What meaning can be found in living out such a short existence... hurting others, hurting yourself, grinding one another down... only to inevitably die and return to dust?"
  • "For someone to gain something means another must lose it... It is impossible to make humankind share limited "things" and "affections"... So I came to the conclusion that everything must be reverted back to where it all began. To go back to when all was one... waves, and nothing else... It is not my -Human's- ego... It is the will of the 'Waves' ...the will of -god-..."
  • "Show me this power of humans! Show me this -love- that you say can make you independent of god..."

    Karellen weeps.

  • "Now there is no more god. This is no longer their planet, this is your home planet that you are now standing on."
  • "Since that time, I have stopped being human. I have committed so many sins that any attempt at living as a human is impossible. The only one who could have forgiven me is..."
  • "Always the peacemaker, eh Lacan? But, regardless, I cannot go. It is something I have already decided. I'm going to walk with god, even if there is no place left for me upon my return."


Blue-haired Karellen in Nisan flashbacks.

  • Karellen, understandably, calls Fei "Lacan" and not "Fei", due to fact that he's known his past life a lot longer.
  • In his final scene, Karellen says, "The only one who could have forgiven me is God." From the English dub it isn't clear if the final word is "God" or "gone," but in the Japanese version, he says god (神, kami).
  • During the game, Karellen appears with blonde-colored hair. In the Nisan flashback scenes, however, he has midnight blue-colored hair. The hair color change is never explained in the game or in Perfect Works.
  • The name Karellen is a reference to a character in Arthur C. Clarke's novel, Childhood's End. In their respective stories, both characters take it upon themselves to serve as a guiding force for all of humanity, with the intention of helping it to evolve to a higher form. Coincidentally, the author and Karellen's English voice actor both share the surname of Clarke.
  • Karellen's ultimate goals and final plans bear a striking resemblance to the theological idea of apocatastasis.
  • He shares many traits and parallels with Xenosaga antagonist Wilhelm.
  • Karellen also has many similarities with the Xenoblade Chronicles 2 character Amalthus.


  1. Perfect Works, pg. 170.
  2. KRELIAN: How can you be so sure? Humans will never come to understand each other. You said that she is the person you love. But can you say that you even truly understand each other? All humans do is place themselves at a comfortable distance from each other and call that 'mutual understanding', 'spiritual unity', or 'true love'... but it is all lies! Man cannot associate with others without first deceiving themselves. That is the way that they were created. FEI: But one being's ego can't determine everyone's fate! People have the right to choose their own destiny! That is why humans have free will! KRELIAN: And what if that 'will' itself was predetermined? What then? Oh, what folly!? Humans are just primitive life forms that have no such things as free will... Mankind has merely been allowed to live in an imperfect state... "as is", "as will be"... It is for this very reason... because humans have this wretched 'will' or whatnot... that humans must experience sadness and loss. For someone to gain something means another must lose it... It is impossible to make humankind share limited "things" and "affections"... So I came to the conclusion that everything must be reverted back to where it all began. To go back to when all was one... waves, and nothing else... It is not my -Human's- ego... It is the will of the 'Waves'... the will of -god-...
  3. ELLY: "Fei... It was Krelian... Krelian released me..." FEI: "Krelian...?" ELLY: "Yes. I came to understand after becoming one with Krelian... His heart was so full of sadness. That is why he desired for he and I to become one with god... Because that would be the return to the beginning of everything... He told me... "You should be with him..." That is what he said... You see... He already knew! Yes, he already knew... how I felt, how you felt... But there was nothing we or he could do... He had no choice but to go forward... even if it meant he lost all feelings, lost everything that was human! For all humankind's sake... There was no going back... Even looking back held too many memories... And he would have... just wanted to go back... Even though he couldn't... So please forgive him... Krelian loved people more than anyone else..." FEI: "I... I, somehow... knew it all along... I just knew he was really that kind of person..."
