Nynallin, anti-mage assassin

Less a certain character right now than an idea...  Anyway, one thing Loreane's setting seems to do is make me draw more complex character designs...

The idea here is that she'd be an anti-mage assassin with her power coming from her tattoos and their exposure to air. She'd normally go around fully dressed so she doesn't display unnatural power until she's close to her target, then she dresses down and powers up.
Her tattoo is a rare sort of magic that can be used by non-mages but is a huge investment, so her sort of assassin is pretty expensive - but in a world that's as destined to be a harsh Mageocracy as the Loreane-Estella setting, any sort of counterbalance is likely welcome. She can change her stats at will and her tattoo reflects it. White is an all-around power boost while red would focus on mostly enhancing her strength. Blue enhances her durability above everything else, yellow her speed, green is a healing state, there might even be a few others like a jumping (orange maybe) or specifically magic-resistant (purple perhaps). Her heavy weapons propelled by super human strength can do damage to even battle ready war mages but they mostly rely on being lined with anti-magic metal to kill the more powerful mages.

I'm thinking if she ends up a character she's kind of the 'once bought she stays bought' type but her job type requires she's not much moral than that. Theoretically she could spend one story hired to off Syrene and another to off Estella. Just as examples, though I probably won't throw her against main characters too often.

Clearly she's a Drow Elf in contrast to Loreane's Wood Elf ethnicity, I just have to figure out what I'll do to distinguish High Elves from both.  As important as they are to Estella's background they probably have to show up at some point.
