Once had a god set up that was actually three gods inhabiting the same form. During an ancient war among the gods they realized they couldn't defeat the evil elder god without more power so they fused into one being. It allowed them to destroy the elder god (whose power fell out among his followers creating a number of minor deities who have been tracking down and killing each other to gain the power that the killed contained), but they were not able to separate once the battle was over. The end result was that the gods constantly warred with each other for control of the form eventually going insane. Their followers are some of the most feared because their fervent devotion to the united gods (simply known as The Three). Most of the Three's followers are as insane as the gods themselves.
