Hello, everyone! I'm Seven, and will (hopefully!) be bringing in Raziel, aka Lily Keeling.
Raziel is the Angel of Mysteries, and basically spends her time learning things, finding stuff, and helping out mortals who ALSO want to learn things and find stuff! Her mortal guise is Lily Keeling, owner of the antiquities store Ephemera, which operates as a sort of supernatural library (she knows or can find something about everything), a safe haven, and the world's best antique shop all at once.
You can read all about her here, if you want! I'd love for her to have lines with the other angels in game, of course, people who might have tried to summon her or who otherwise sought her blessing, demons/fallen to be enemies throughout the centuries, possible complicated romantic stuff, everything.
