Sacrificial Gates of Segrummar

Sacrificial Gates of Segrummar is a side quest in the The Descent DLC for Dragon Age: Inquisition.

"There are a number of sacrificial gates in the Deep Roads that can only be opened with bloodstained ancient gears. Valta's stone sense is leading her in other directions, but there must be something important behind these gates if someone took the trouble to lock them."

Acquisition
Approach the first sacrificial gate, located beyond the first rune-warded gate in the Darkspawn Warrens.

First gate:
Find 3 bloodstained ancient gears scattered around the area. Once the gears are installed, the following note appears:

"The Gates of Segrummar

Some of the hand-stamped ink letters on this parchment are hastily smeared over each other. Only the following words are legible:

The creator provides tools. Burning wheels lower gates. I break the lines. Forge the broken sigil.

Locked the way behind. Claws raking the door. Scatter all the keys.

What trails my steps? It does not matter. There is only forward."

Pull the lever to open the door.
