The Shadows are an ancient, advanced race residing on a planet at the edge of known space called Z'ha'dum.
They are a spidery/insectoid-like species with great military and technical powers. Very few people know of their
existance even though G'Kar has been warning of an ancient enemy. The Mimbari and the Vorlons know. The
Vorlons and Shadows are long time enemies. About 1000 years ago the Shadows were defeated by a coalition of
alien races and have been rebuilding their forces ever since. They are now strong enough to fulfill their objective of
destroying the universe. They appear to be stronger than the Vorlons. The only weakness of the Shadows is their
susceptibility to telepathic attacks.
