I thought Seraphim as a a sort of Angels' flying counterpart, though not identical to 624, of course. Since these are her first doodles, she just has one set of wings deployed (she has three). In my original conception, Seraphim was a hurricane creator, able to cause great damage with her wings and/or to cause tsunamis with the sonic boom she could also create. She found her place with the owner of a local flight/paraglider club, for whom she will be a trusted partner and a beloved friend.
