3: A Warm Welcome

Groo, Rayna, and Declan arrive at the ruins. Declan recognizes a few landmarks from Moira’s notebook, and eventually leads them to an underground tunnel entrance.
The tunnel is surrounded by a circling mass of 100+ zombies! They all seem attracted to the tunnel entrance but can get no closer than about 50’ to it.
Groo uses his knowledge of stonework to knock down the wall of a nearby building, clearing a section of the zombie horde out just long enough for them to dash through.
First room is a trapped tile floor. Kelley’s two bandits are there dead. Moira is there too, still alive. They rescue her and decide to go in, to ensure Kelley doesn’t get the pearl.
Next they encounter a locked room trap. They’re unable to break free but, after sounding an alarm (there’s no one left alive down here to hear it) it resets and frees them.
Next is the main chamber, a huge spherical copper room crisscrossed with catwalks. There’s a key dangling in the center, plus three other doors out, one of which has three keyholes. They enter one of the side chambers first.
This is the Fiery Treadmill Trap, a room with a sliding floor that moves them towards a wall of flame. Groo and Rayna defeat a pair of flying swords, which serve as the triggers to disarm the trap and release the key here.
