"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-
Chidna, like The Engineer, is strictly not a cenobite, but a demon created by Leviathan to suite the needs of Hell. Leviathan probably created Basalisk and Chidna to entertain the population of Hell, stopping chaos from erupting out of boredom. Basalisk and Chidna danced together in the center of Hell for as long as anyone could remember, but as soon as the Time Configuration started, Basalisk and Chidna started fighting until they ripped each other apart, killing both of them. Chidna is the female counterpart to Basalisk and is serpentine with a humanoid head and body. Once order was won by the Vasa Iniquitatis, Chidna and Basalisk were returned to their natural state and continued their dance in calm.
