Zirrix is a planet blanketed in an ionic, acidic atmosphere with poisonous oceans. All forms of "life" on the planet were bio-engineered to fit the needs of the major sentient species of the planet, the Virin. The Virin are parasites with 30% of their body mass in neural tissue that bond with other beings to control their bodies for their use. The planet is ruled by the Virin Confederacy headed by Jarik Z'kaa.
Th'rix Na'thaar, a Virin scientist without the ability to bond, used an army of Nefadon to create the Nefadon Empire attempted to take over the planet, but then Dark Madder appeared and removed his higher thinking skills, ending the conflict.
