Mole Down, Two To Go
From Tales of Maj'Eyal
Mole Down, Two To Go is a quest in the Embers of Rage campaign. The player is granted this quest when they first enter the G.E.M.
The goal of the quest is to crush the steam giants riding the G.E.M. (and the horrors who got inside), in order to stop any information from getting back to the Palace of Fumes (e.g. about how the player character just devastated the Gates of Morning). This quest is completed when Haze Commander Parmor is killed.
In-story, this quest may not have actually been necessary, because the steam giants were actually fleeing away from the Palace of Fumes and planning to escape using the farportal in the Gates of Morning, but the player character didn't know that.
