Gadit (@thetransintransgenic) is “microficcing the Omer”, ie writing a new Unsong micro-fanfic for each of the forty-nine days between Passover and Shavuot. She hasn’t quite kept to the schedule, but you can read what she’s got here. I’ve helped with this one and this one, which you can consider canon if you want (the others probably don’t fit). The sudden inclusion of transfemale angel Gadiriel is not a deliberate Gadit homage, but you’re welcome to think of it as a sort of unintentional kabbalistic cameo if you want.

75thTrombone is working on a sort of index of relevant facts which might get transferred to a wiki at some point.
