Sadranis returned from the Void with his sanity in question. He went deeper than Emri, survived longer through arcane sorcery, and eventually came into contact with a certain being that decided to use him for its own ends. He now returns, changed physically and mentally, a window into the mortal realm through which an unknown power watches, content to wait...for now. Physically, he has also changed - he has a cluster of tentacles emerging from his right sleeve, projecting from his body.
Sadranis formed his own clan of demon slayers, a sorcerous parallel to the Black Watch (Nihilmancer)
With their abilities augmented by Hedron technology, Sadranis' followers were able to venture even further into the Darkness. (Nightmare Delver)
