Zavarov is a planet in the star system Vartas. Zavarov is located near Old Miltia and is one of the core worlds belonging to the Salvator Faction.
Since it belonged to a solar system near Miltia's, it became the base of operations for the Galaxy Federation Peacekeeping Detachment Fleet during the Miltian Conflict. Helmer was stationed there.
It is also the world on which the Yuriev Institute, seen heavily in Episode II, is located. Dr. Juli Mizrahi and her daughter Sakura lived on Zavarov after her separation from Joachim Mizrahi. Sakura was brought to the Yuriev Institute for treatment of a central nervous system disorder.
