Ahh Galveniit, an adopt I picked up that fit quite perfectly for a role in my expansive lore that I have no desire to write down anywhere out of laziness.

He stands as the being that controls the black corruption within Thunder's very core, both keeping him alive in times of need...and hindering his mental state in times of despair. They have a rather unspoken bond with one another, one that is mutually benefitial rather than one sided

But, regardless, this amazing character I got from  LumixDragonFey!
