The gates to Gehena

The gate to Gehenna, is the result of an experiment carried out by the necromancer witches millennia ago, even before the imposition of the current new leader of the witches. His intent was to summon an army of the dead from Hell itself, however it wasn't just the dead that they released through the gate. Whatever it was that came out of there, ended the lives of all the necromancers as well as destroying the tower where they ran. To avoid greater evils, Arachne, one of the three most powerful witches, invoked her brother Phalanx, turned into a spider to serve her sister and to guard the door so that no more dangers would come out of the gates of Gehenna.
