The Ashland Dome Ruin is an Ancient Location controlled by Ancient Ruins. This location does not have any inhabitants or spawn any loot. The location can be marked by reading the Old Treasure Map, indicating that not long ago this place was worthy of a visit. There are two Ashland Dome Ruins in the Ashlands.
Given their placement in Ashlands relative to other Ashland Domes, it is possible that there were other 2 high-ranking officers of the defunct Second Empire in these domes, but they were destroyed as a result of the building being ruined. Either that, or the placement of these buildings are purely aesthetic.
