Derelict Pumphouse

Derelict Pumphouse is a small Dwarven ruin in Blackreach occupied by a Dwarven spider. It is located on an island in the waterfall-fed lake in the southeastern part of Blackreach.

Interior of the pumphouse



There are two entrances to the Derelict Pumphouse; the lower entrance is accessed near the water's edge, and the upper entrance is a lift reached from the walkways high above the lake that lead to Raldbthar Deep Market. Three geode veins are found around the lake the island is in the middle of, with one to the east of the lower entrance, and the other two near the bottom of the stairs leading down to the lake from the War Quarters. There are several crimson nirnroots around the lake, with one on the west side of the island with the lower entrance, a second behind a waterfall due south of the island, another near the shore by the two geode veins, and another slightly farther up the stairs near a broken pipe spilling water. Farther up the stairs to where they split, follow the path to the right to find two frost trolls and another crimson nirnroot. There is a sixth crimson nirnroot near the pumphouse that can only be reached from the top of the lift (see notes).

Derelict PumphouseEdit

Entering through the lower entrance, you emerge in a partially flooded room guarded by a Dwarven spider. Across the bridge ahead is the lift serving as the zone's upper entrance, from which you may access the Blackreach exit from Raldbthar Deep Market. On the right are stairs leading down into the water, with an adept-locked chest on the wall. Under the bridge is a crimson nirnroot and an unlocked chest. To access them, you will need to jump over the pipe to the west of the bridge and activate the valve under the water on that side, lowering the nearby spears under the bridge. A second valve under the bridge lowers the second set of spears, allowing you to use the eastern stairs to leave the water.


  • There is a crimson nirnroot that can only be reached from the top of the lift. It is due west, between two waterfalls on top of a large rock. To reach it, travel up in the lift, turn to the west and walk to the edge, then use a single word of Whirlwind Sprint. This should allow you to land right in front of the nirnroot. There is also a patch of fly amanita at the same point. Be careful: if you overshoot, you may die from the fall.
