The Geothermal Exploratory Mole, or G.E.M. for short, is a tunneling vehicle created by the Atmos Tribe, which serves as a zone in the Embers of Rage campaign. It emerges near the Gates of Morning after the player completes The Deconstruction of Falling Stars. Entering this zone will grant the player the quest Mole Down, Two To Go.
The first floor (40x25) is outside, with grass and trees, but contains the entrance to the G.E.M. itself through a breach in its hull. The enemies on this floor are plants. One can find the Half-Mechanized Yeti required for the Mystery of the Yetis quest here.
The second floor is (60x60) is a mechanical type, and the third floor (30x30) is the command deck. The enemies on the second floor are steam giant warriors and gunners, and mecharachnids. The third floor has those enemies plus horrors. Needs verification: Hand-placed enemies on third floor? The second and third floors have vinyl disks, which contain lore, but the player must take them to the phonograph player on floor 5 of the Palace of Fumes in order to listen to them.
