Osiris's Egyptian image was altered based on the realm that he would occupy and choose to represent. The panthers within the room purred and cuddled the vine-covered god, praising him as if he were the only one who wielded such power. He brought them to his chambers and they provided him some flesh of satyrs and some humans. However, there was someone beside him in the shadows who was only to observe from a distance.
Osiris's form became Bacchus, or Dionysus as the Greeks called him. People who weren't familiar with the mythos believed that Osiris may have been the leader of the Egyptian Pantheon. His role in it started when he was a babe of Zeus. Though, as he released his 'mask' he could rule the realm of just simple subjects.
