Dark star
From Tardis Wiki, the free Doctor Who reference
A dark star is a star with devastating psychic powers. If a human mind comes within close proximity of such a star, the mind will be overwritten with primal instincts long since lost to humans.
Biological Composition
A dark star is made from sentient hydrogen cells infused with z-neutrino energy. It is unknown how the star possesses psychic abilities. A dark star is different from a black hole in that a dark star reacts just like a normal star and even has solar flares. It is called dark because of its degrading effect on the human brain and it's colour which is deep black.
Other Information
There are only four dark stars in the known universe one of which is in the Silver Devastation. It is thought that a space-time rift is located at the heart of the star.
