Calamity

A rather chaotic bismuth crystanium entity who does whatever he feels like, Calamity is an annoying guy who shows up, causes chaos, and then fucking dies. While the net is currently working on a way to render him permanently dead, that hasn't been figured out yet. His favorite hobbies include giving people things with random results, creating deals where he gets souls, being a general bastard, messing with Sera, and doing things without absolutely no ramifications for their consequences.

Not much is known about where the hell Calamity came from. He just showed up one day. However, it's been deduced that Scale is to blame for his existence, likely through a similar process of how The Librarian was made.

Personality
Calamity takes on the idea of chaos as a rule, doing things for seemingly no particular reason - but it always so happens to be always horrible things. He has no qualms about torturing people with his powers, creating chimeras that suffer by their very existence, and destroying any planets. He appears to have a particular like with messing with Seraphim and Adryel, though perhaps that's simply due to the drasticness of his shenanigans.

Despite having the capacity to do so, Calamity rarely ever bothers planning his actions, mostly due to the lack of any practical goals beyond causing problems on purpose.
