Ralvash

Ralvash is mentioned by Azzanadra, as a Mahjarrat who "faced the void" in the last Ritual. This is likely to be a form of banishment, as the Mahjarrat seemingly cannot be truly claimed by Death. Imformation from Jhallan seems to contradict this, however. He is also mentioned by the Chaos Elemental. 

It seems he was the weakest Mahjarrat at the time of the last Ritual, as the Mahjarrat sacrifice the weakest one of their own in it.
