The Eyeless Web (Underground Ulos, Cahyali)

Party got hired to steal a monster that was captured by a clan of spider people + their allies. After being transported to the deep underground fortress beneath Ulos, they attempted to use Acting & Disguise skill to convince the guards that they were there to purchase the monster. The guards saw through the deception, but countered it by pretending to fall for it, and then luring party into a trapped room. Party proceeded to fight for their lives, win, and escape. Following that, they located the monster and extracted with it.
