Hello all I must ask before making the attempt because I really want to fully develop the character.

My concept is based in Lovecraftian, something beyond heaven/hell.

The creature is a being of experience as a living avatar of Yidhra, the Dream Witch.  Utterly insane, it changes itself to appease its unknowable Mistress as she slumbers.  Yidhra must be entertained in her dreaming, lest she awaken from boredom, devour the world, and become it.  Not much is known what happens next but it cant be good.

Initially I had an idea that this thing, while initially worshipped by small cults, was contained following a raid.  The very nature of it made containment in some room not a favorable possibility.  It is now utilized as a type of attack dog for the bureau, and give useful if entirely random insights into the super natural world.  A dangerous asset.

Would this work?
