You will soon come to a massive central chamber where a group of deceased mercenaries had set up camp.
Head inside the dungeon and you will quickly notice that these natural caverns actually contain a large Dwarven ruin. Activating this strange relic will begin a separate quest called The Dwarven Horse to reassemble the construct, which can be done in tandem with this quest. The cave has an unassuming entrance located just west of Lost Valley Redoubt you will know you have arrived once you see the torso of a broken Dwarven Horse. You will be directed to Runoff Caverns, an undiscovered cave far south of Rorikstead which will already be marked on your map. This quest will be added to your journal upon installing the Forgotten Seasons Creation.
