The other group of recruits from the temple.
Lamsin was their leader and left the guild after the mission to do freelance adventuring.
Agrippo was their muscle. A showboating warrior who enjoyed sparring and crafting. Ended up dying in the temple when he abandoned the group and was (presumably) killed by the rising lava in an attempt to steal a statue from the tower.
Mendri was a mute whip weilder who turned out to be some kind of flesh golem who was reset by a conflict with siders. The party tried to send them to the surface for safety but they appeared to be kidnapped at somepoint between getting on the elevator and reaching the surface. Ultimate fate unknown
Olemar was a wood elf archer(?) who had goals in seeking out someone from their past. He was bisected by a lava worm and was narrowly saved from death by the combined efforts of Ariana, Imdran, and Impel, but still lost his legs. Was given a use of the scrying spell as consolation.
Galthasar was largely forgettable. Was a good friend of Olemar. the two of them went to pursue his personal quest after quitting the guild
