So I drew something. It's a few months old by now, but I considered uploading her skin soon, so I thought it fit from the time & such.

Her name's Aoife Llewellyn, she's an endboss-level threat and the main supporter of Raido the wolf girl, as well as her antagonist.
She's a manipulative deity of eldritch descent, who spent most of her modern years in Ireland because... She's... celtic? I guess? I don't know how I came to that conclusion.
She seems humorless and cold, but in truth, she's a highly calculating ego-maniac.
She's basically like an animal that needs to feed;
She doesn't care about who gets hurt or why, as long as she gets her food.
Her food being wars, that is.
Aoife works something like this-
every victim of war, every soldier (alive or dead), every civil casualty or warmonger counts as a sacrifice to her.
A sacrifice means that people worship her which, in turn, provides her with power and energy.
She's a rune smith by default, a sort of magical rulebreaker. Runes are what keeps the magic alive. If you can make your own sigils and runes, you're basically undefeatable by any means.
But that won't stop Raido. Aoife must fall.

This cruel god must pay for the betrayal! Must pay for her lies! MUST PAY FOR THE PAIN SHE CAUSED! MUST PAY FOR ALL THE WARS IN THE WORLD! MUST PAY FOR EVERY MISERY!
