The Ravens

The Ravens, also the Rah'havens, are demon hunters based in Ienda, in their castle of Raven Rock. Rah'haven is Iendan for Demon Hunter. When the Resarian Imperium came to Ienda and brought the Resarian language with them, after noticing the similarity between the word Rah'haven and ravens, they picked the raven for their sigil.

Their mission is to fight and destroy demons and warlocks across the land. There are typically around five hundred to a thousand members.

The Ravens are promenant in the Alessya Dagwyn books as she is a Raven and a protagonist.
