Raviel

Raviel is the Celestial GateKeeper to the mortal bound dimensional gateway. Completely invisible to mortal eyes with the exception of yours, since you are a true Celestrian, and she can sense it. She spends most of her time sitting on the countertop in the Questers Rest, listening to patrons, and visitors tell their stories and talk about the things they've seen. She has an insatiable curiosity for the human world and is eager to learn more about their culture. She comes off like a cool big sister, if someone aloof. She doesn't really get many visitors so she'll let you use the gateway that she's guarding for free, unlike most Celestians she lives in the mortal world and is not really interested in the end goal of the Angels to becoming Stars. She's also the younger twin sister to your master Aquila, which gave you quite the shock. Since your master never told you once that he has a twin sister.
