You could always find a name that generally means rage/warrior or something. Combine him with a few gods or just make him a prankster like Puck, only a lot worse.

We can say the gods are vaguely related? I know my girl wouldn't willingly talk to the others unless she was related/needed someone to help with this community. She's sympathetic towards humans and quiet. Your god might be loud and different than her. Them doing this, well they're gods. They like to fuck around with people.

And I yanked this from her profile page: Unlike the other gods lurking on the community Kelt is calm, quiet and generally sympathetic to the plight of the humans who her fellow gods torment. Even with her ever changing appearance and distaste for bright lights you can say that Kelt is one of the kinder of the beings who control the community. Even if she does ask for compensations when curing those who have been afflicted with whatever the other gods have thrown at them, she is hardly demanding much. A simple sacrifice or token of a beautiful mask will appease this goddess.

But its best not to anger Kelt, even if its hard to truly ruffle the goddesses calm exterior she does have a temper one should be advised not to cross. Though she's not the most powerful of the gods she can change peoples bodies at will and would punish those who have pushed her limits.
