Billos was loyal to the Forest Guard and a lover of Darsal, but was very flawed. He had a great hunger for power, and was easily won over by Marsuvees Black. He was constantly trying to get the others to use the books. In Renegade, he used the books to go into the Paradise simulation, where Marsuvees Black gave him "suhupow" and forced him to massacre the town. Elyon in boy form led him to a lake, where Billos found how he had been so terrible. When he travelled back to Other Earth, he appeared in Alucard's lair. Because Darsal had made the vow, he couldn't travel into Earth. He was thought to be killed, but he was revealed in Green, as Ba'al the dark priest. His counterpart is Billy Reidger
