As I've said before, anyone who doesn't mind (hopefully constructive) criticism is welcome to post here, though I'm only putting my stuff in the index.
And...we've never seen Mavra actually fight, so I feel like statting her is premature. She's smart, has Wizard-level magic, something like Kemmlerian Necromancy, and is good at veils...but that's seriously all we know. Skill-wise, she's probably Superb in Intimidation and Deceit, plus maybe some magical skills...but again, that's approaching all we know about her beyond the Black Court basics.
The Eebs are more doable...but not that interesting (being mostly bog-standard Red Court plus a little mental mojo and Pack Instincts for their bond with each other...plus pretty good skills, I guess). I guess I could throw 'em up though.
