The deepest tier of the caves in fact are dwarven ruins, a roadway, once created by "Royal Order" from King Kelgak, to connect the thaigs of Aeducan and Gundaar – in its center a hall, to honor the Paragon Hekkat and his "Principles of Nature".
Whilst one exit emerges directly to the surface into Crestwood's East Side Hills, the upper tiers of the now abandoned ruins in the Deep Roads lead into a network of caverns above, which eventually exits to the old Crestwood village.
According to the Mayor of Crestwood's official statements in 9:41 Dragon, the caves' most recent use was during the Fifth Blight: refugees took shelter, fleeing darkspawn. However, the darkspawn subsequently broke into Caer Bronach, wrecked the controls for the area's dam and finally flooded the old village and the caves.
A Fade rift opens in the flooded caves, resulting in demons crossing the Veil from the Fade, possessing the various corpses left from the Blight and creating a swarm of undead who lay siege to the Village of Crestwood. The Inquisition moves into the area to protect the settlement and raid the caves to seal the rift.In the process clues are found that tell another story about what happened at this place during the Fifth Blight, and after the waters have been stilled, Crestwood's mayor confesses his involvement and his guilt as being himself the person responsible for the flooding, with the intention to save the remaining healthy inhabitants of the village from the darkspawn and the taint of the already infected people.
Codex entries Edit
- After completion of the quest Still Waters, the Flooded Caves are a good place to farm the tier 3 metal Stormheart, along with its tier 2 counterpart Paragon's Luster, as the caves are free from enemies then, and between 30 and 50 pieces of Stormheart can be collected during one passage. In addition, a Royal Elfroot can be found at the pond near the East Side Hills' exit.
