Right, so. I have been meaning to make a proper ref of this thing for a while. Ended up kinda text heavy, and there is a lot more I could add :x Parts probably don't make much sense without going into more depth about the world it lives on and other creatures and concepts that live there.
Much wtfery..

Other background info -
The zarathus was first created when I was 12, its design based upon an interesting natural pattern I found in a wooden panel on the ceiling of a factory office, in a run down industrial area. The name was borrowed from a sea dragon character I had created years earlier.
The original zarathus had an entirely different appearance, was male, and was not intended to be “me” in any way. Somehow this creature latched onto my mind unlike any others had, and after writing a story in which the main character, zarathus, represented me, I became obsessed with the idea. Unfortunately that hasn’t really changed since. :|
Its appearance and personality have changed a lot over time, pretty much changing to fit however seems to express my brain best to me at any given time. As such the zarathus has no solidly defined form, or any definite character background or history. It is generally just a solitary wanderer used as a tool of expression.
Its literal background could be interwoven with its fabricated one, being a creature created through a tree (sesraw) and being adapted and modified over time. As well as having a curious affinity for urban/industrial decay.
Has loose associations with other creatures such as california condor and hyenas. Was created by/pestered by demons, guided by dragons and a friend to canids.

Edit: this is now kinda outdated and lame, some/a lot of the info has changed..
