A teenage girl with antlers, dressed up as Toriel, lounged in the quiet room, crocheting something and snacking on a stack of cookies she'd picked up from the snack bar.
A pair of elven women were also sitting in the quiet room, arm in arm, chatting softly. One, a smallish wood elf, was in knight armor, while the other, a tall high elf with dark hair and an androgynous frame, wore a long purple princess gown.
Over in the main room, a half-elf dressed as a satyr leaned on the wall near the tables, with a little elven girl in a valkyrie costume bouncing around at her side.
Three women sat around a table, all dressed in Obligatory Ridiculous Sexy Costumes. They were a high elf, a wood elf, and a human, dressed as an eggplant, a squeegee, and a tennis racket, respectively.
A tiefling and a human danced together, dressed up as an old married couple. The tiefling wore a nightgown and had curlers in her voluminous green hair, while the human had pinned her hair back to look short and worn a bathrobe and fake glasses.
Someone unrecognizable behind their tree costume stood somewhat awkwardly in the corner, trying not to poke anyone with their branches with little success.
An elf wearing butterfly wings stood frozen in the doorway, unsure what to do.
A dark-haired man - on closer examination, he had cat eyes, so probably a witcher - danced with wild abandon, dressed up as Nasuverse's interpretation of Cu Chulainn.
Two winged twentysomething women, both dressed as birds, were methodically sampling all the appetizers.
A brother and sister in ornate robes, wearing beaked masks of woven straw but not dressed up as anything in particular, observed quietly from the drinks table, somehow still standing up perfectly straight after a worrying amount of brandy.
Someone who'd just draped a bedsheet over their head, without even cutting any eyeholes, and called it a day picked their way through the crowd with perhaps a bit more confidence than might be expected from someone who couldn't see.
((Apologies for dumping my Entire Enormous Roster on the thread, but I couldn't pick ^^;))
