This angel could report to any number of masters such as Lolth, Tiamat, Zehir, Vecna, the Raven Queen, Sehanine (trickery), or even Tharizdun. At third level this angel can run away to harry the party again later if he succeeds with blinding barrage to cover his escape. I didn't choose Stealth training because I wanted some roleplay interaction between this angel and the party but Stealth works for other concepts. Imagine this angel with Stealth tracking the party and "joining in" on other encounters the party faces each time fleeing to return in another encounter the same or next day.
