Hey all, I just wanted to post a small detail about Peryite that has been posted on the Elder Scrolls Online website. It is a small bit but it is at least something more about a Prince that we know little about :

A servant of Fa-Nuit-Hen responds to a qusetion with :

"particles of chaotic creatia, when flowing in reaction to the exertion of will, become daedrons that, though injurious to the mortal form, can nonetheless perform work. Underutilized daedrons usually return to quiescence—but if imbued with sufficient purpose, they may escape and coalesce to form potentia vortices. These are dangerous if allowed to self-optimize into realm-rips, so it's best to damp them out early. Trying to keep ahead of it all keeps Peryite mighty busy, but nobody's really sorry for him—after all, he earned it."

So there you have it, a small detail we did not know about. Even if it doesn't have anything to do about diseases, except in a roundabout way, removing "diseased" parts of Oblvion, although it more fits with the ordering of the realms of Oblivion.

Seems very consistent with everything put forth about him thus far. The "Pus in the wound" anology seems very fitting in this context.
