At The Top Of A Waterfall In The Lightless Hollow Skyshard

Guide:

The Lightless Hollow waterfall is actually not on the Western Skyrim map, but in Blackreach. That is also part of the Greymoor expansion, and in order to reach it for the first time, you’ll need to find one of the greater lifts on Western Skyrim. The specific one we’re talking about here is the easternmost place of interest on the map, where the main road ends in a kind of small dead end.

If you follow the road east from the Morthal settlement and its Wayshrine, you’ll pass the Hailstone Valley ritual site and notice a small stone gazebo with a lever at its center. Interact with this lever and you’ll reach the east part of Blackreach: Greymoor Caverns. Just south from your landing location, you’ll find the Lightless Hollow Wayshrine. This is your first “checkpoint”.

From the Wayshrine, follow the road south by sticking to the eastern part of the caves. If it’s easier, keep to your left here the whole time. The goal is to reach the end of the longer passage where the waterfall starts. Once you enter this passage near the Wayshrine, you are pretty much set, as it takes you straight toward this spot. The shard is on the rock that divides the waterfall into two streams, close to the edge, so be extra careful.
