Uferbruht is the black winning king and qualifies, while Aimūlli is the white losing king and it's eliminated.
Also Aclaira is out, as it was matched with the killed white pawn. So, if your piece is killed, that also means you're out!
Congrats to all the qualifiers so far! Love this results concept I wish I could join in, because it seems super fun, but unfortunately I'm working today Maybe I'll be able to come by for a riddle or two at some point though.
