And, based on that last story, it looks like I’ve elected to use the Egan-style ve/ver/vis pronouns for the neuter gender (the friend, although it never comes up, was a kaliatar; a neuter member of a trisexual species).
Still haven’t settled on which English pronouns to use for herm, though. Hm. (And part of me is now trying to remember unsuccessfully which pronoun(s) Bujold used for Bel Thorne, et. al. in the Vorkosigan books. Not that fiction-writing has binding precedents, or anything, but still. Curious.)
