After an extended stay in solitary confinement the Eldarin Ariethlan (or “’arry” to the prisoners too uneducated to pronounce his name) is summoned to help save the lives of prisoners trapped in a cave-in. Using his power to shift between spaces, Ariethlan bypasses the cave-in and commences rescuing a number of prisoners, including Argus (a hulking Draconian fighter) and Carric (an Elf rogue). They proceed to rescue other trapped prsoners, along the way fighting a hungry carrion crawler and some shadowhunter bats.
After discovering that some of the prisoners are in fact doppelgangers in disguise (the hard way), the party and the doppel gangers eventually fight each other to a standstill (with more than a little help from “Muddy”, the last surviving prisoner), and discover that the cave-in was deliberate, and part a plot to invade the Crimcooper Mines from below. The party and the doppelgangers share information, and it is agreed that the party will continue down below to fight the Duergar scouting party that plan to invade, and the doppelgangers will assume the identities of the party and go above in the hopes of making an escape. Muddy agrees to try his luck with the Doppelgangers rather than face certain death below.
The party make their way further below and ambush the Duergar camp. After a particulailly tough battle they are victorious, and have enough supplies to survive down below for a few weeks. Hopefully they can find an exit to the surface before they run out of food.
