"Their double-helix dance steps mirroring the grace and power of Hell's own patterns"
"Ravaging anarchy whose reflection can only spread outward in the pool of the abyss."
-Description of Basalisk and Chidna's dance pre and post Time Configuration-
Basalisk, like The Engineer, is strictly not a cenobite, but rather a demon created by Leviathan to maintain order in Hell. He and Chidna, also a demon, dance in the center of Hell. The reason for their existence is most likely entertainment. When the Time Configuration began, Basalisk and Chidna started to fight and eventually ripped each other to shreds, killing both of them. They both appear as snake-like creatures with humanoid heads and bodies, although Basalisk is more masculine as he is the male counterpart of Chidna. Once order was won by the Vasa Iniquitatis, Chidna and Basalisk were returned to their natural state and continued their dance in calm.
