Mandragora Helix
The Mandragora Helix was an intelligence composed of helix energy. It existed in its own domain in “unchartered regions of the Time Vortex”.
Origins
The Helix originated in the Dark Times.
Physical Appearance
It was a spiral of pure energy that radiated outward, being able to draw things into it. Inside the Helix was a black void where sound echoed and a series of concentric crystal rings stayed suspended. There was a form of ground inside where beings could walk. Balls of energy would bounce around the void.
The Helix was often mistake for a star but it was actually a superheated ball of psionic energy.
Powers
The Helix was an intelligent astral force capable of speech. It could easily infiltrate human minds. With humans, physical contact resulted in instant death a a blue crystalline growth on the skin. The energy took over human bodies giving them a white appearance and allowed them to fire bolts of energy from their fingertips.
It could travel through space but in some cases, could only reach its destination when the stars lined up in a certain order.
