Cylosis
From Wikitroid, the Metroid wiki
Cylosis is given as Sylux's origin in the opening cinematic of Metroid Prime: Hunters. Since Sylux is surrounded in mystery, it's debatable whether Cylosis is Sylux's actual homeworld, or simply where Sylux stole the armor, Delano 7, Shock Coil, and Lockjaw.
The opening movie to Metroid Prime Hunters shows a location that may represent Cylosis as a plain and lifeless-looking surface, with blue-gray dust (or possibly snow) storms.
[edit] Name
