I've always felt sorry for Peryite. He's responsible for diseases, and takes the form of a huge badass dragon, but many sources state that he is in charge of only the lesser planes of Oblivion. Is there a reason for this? What exactly do we know about Peryite anyway? What makes him weaker than the other Princes? His realm also appears to resemble the Deadlands in many ways, I'm presuming that he's one of the more evil (yes, yes subjective and all that) gods?

Is it fair to say that Peryite is perhaps one of the more obscure gods in TES lore?
