The Angel of Sound

Tru'nembra, The Angel of Sound, is an Outer God who resides eternally in the Court of Azathoth. Your patron does not possess an instrument for he himself is an instrument. He is made entirely out of visible noise and is seemingly unintelligent, just like his master. When your patron is summoned, it brings along the maddening symphony it uses to keep its master asleep, bringing insanity to those who are unfortunate enough to hear its blaring chaos.
