Xenogears - Soylent System scene

Fei and Elly are horrified after realizing what Soylent is made from.

The Soylent System is a huge Solaris plant that was first connected to Karellen's Lab before being moved to the ground. Erich Van Houten was one of the facility's superintendents, but he resigned out of guilt.

The plant is just one of many Soylent System facilities, not just in Solaris, but also in secret locations on the earth. The Ethos are responsible for overseeing the Soylent Systems.

The Soylent facilities were established in 9499 by the forces operating Solaris, during the Shevat-Solaris War, where they were first used for biological and brainwashing experiments.

Both Solarians and Lambs are are unaware of what the Soylent System is or does. Elly says, "I've heard the Soylent System is an important support system for Solaris, but I don't know much else." The only exception to this seems to be those who control the facilities, such as Erich.

In truth, the Soylent System facilities are where humans are transformed into Wels, and, subsequently, food and medicine. This is for two purposes:

Citan reveals to Fei that Solaris put additives in the food and medicine to control people.

  • The first purpose is for the food and medicine is given to the population of Solaris and the surface, giving them a source of additives to control people's behavior as well as a way to maintain the seal placed on the populace by Limiters.
  • The second purpose is for the Wel bodies collected to be used for System Deus, as part of the Gazel Ministry's M Plan.


After learning about the disturbing nature of the systems, Fei Fong Wong and his allies went from place to place, destroying all the Soylent System facilities located on the surface of the earth and freeing people held at each of the locations. All the people that had been mutated were taken in by Nisan where they received treatment.


  • "Soylent System. The organism experiment lab and its disposal facility in Solaris. And the production facility for food and medicine to maintain the Limiter seal. Aquvy's Wels Reapers were also made here." - Citan
  • "The Soylent System... A group of facilities formerly created by Solaris. These facilities existed all over the earth. It is said, that, originally, these were used for biological experiments and brainwashing." -Elly


The name is a reference to the dystopian movie Soylent Green. Soylent Green is set in the year 2022 in an overpopulated New York City, where humans are secretly processed into green wafers called "Soylent Green" (as the other varieties are not made of humans) and subsequently used as a source of food, a horrifying fact that is discovered at the film's climax.


  • When Fei finds out what food Soylent makes is made of, he has a vision of his mother, as Myyah Hawwa, experimenting on his "coward" personality.
