The party began exploring the mirror dungeon, where they found that from the beginning they were being watched by a scrying sensor. The dungeon involved a series of magical puzzles, including a tunnel traversed by reversing gravity, a tunnel which appeared to be straight but was actually bent and used mirrors to create the illusion, and an area requiring them to go into a mirror of life trapping in able to get past.
The party was eventually able to find a mirror device that created temporary copies of items put inside, that could be used to duplicate temporary items (like potions) or enhance permanent items, though at the risk of damaging the mirror.
They eventually got to the end of the dungeon where the Mirror Wizard had set up a series of mirrors to create an infinity effect, making it difficult to traverse the room or identify which wizard was which. Using a confusion effect he disabled Tiffania and Lady Belmont, while Nyanta found him with stealth, and Ivan countered his spellcasting and his echolocation senses with silence, eventually beating him.
They raided his treasure, and learned the secrets of his mirror of life trapping, which they used to free a Deva Angel(who taught them one of the saving throw feats), a Nymph (who gave Tiffania her favor), a Unicorn, and Sanders, a human ninja who had gotten caught in the mirror- which they were able to recruit as a guest.
The party then went home to use a week of downtime.
