Vilgaxia (formerly known as Murray) is the Chimera Sui Generis homeworld.
Vilgaxia was introduced in Ghost Town, where Zs'Skayr attacked Vilgaxia, possessing all the citizens and turning them into his Ectonurite slaves. After several vain attempts to stop the infestation (including alternating the planet's sun constitution so its light would weaken Ectonurites), Vilgax escaped Vilgaxia and asked for Ben's help. Despite their differences, Ben accepted and after some complications, freed the planet from Zs'Skayr's control. As an agreement between them, Ben promised to not tell anyone what happened there, and Vilgax gained credit for Zs'Skayr's defeat.
Vilgaxia was mentioned in Vilgax Must Croak, when Milleous attempted to capture the planet. However, he was unable to; due to Attea's failure in killing Vilgax, the citizens learned about the incident and put up a massive resistance, forcing the Incurseans to retreat.
Little has been revealed about Vilgaxia so far. Vilgaxia includes a large city with a large, fortress-like palace, home to its current ruler, Vilgax.
The atmosphere is teal in color, temporarily dark orange during Ghost Town, and looks as if the surface is underwater. Closer to the horizon the atmosphere fades and reveals space. The atmosphere also makes it impossible to see the terrain when the planet is viewed from space.
Some of the known terrain consists of light green mountain ranges.
