Dark star

A dark star was a star with devastating psychic powers. If a human mind came within close proximity of such a star, the mind would be overwritten with primal instincts long since lost to humans.

Biological composition
A dark star was made from sentient hydrogen cells infused with z-neutrino energy. A dark star was different from a black hole in that a dark star reacted just like a normal star and even had solar flares. It was called dark because of its degrading effect on the human brain and its colour which was deep black.

Other information
There were only four dark stars in the known universe, one of which was in the Silver Devastation. It is thought that a space-time rift was located at the heart of the star.
