Hag's End is reachable through Deepwood Redoubt, northeast of Markarth. Here, you'll chase a Hagraven as she teleports deeper and deeper into the dungeon. Eventually she'll teleport outside, to the highest point of Hag's End, for one final showdown. Hagravens are punks, and the creatures she summons are bigger punks. This dungeon is home to one of the words for Tiid Klo Ul. That's "Slow Time" for you non-Dragonborns.
The coolest thing about this dungeon is the secret lever that spawns behind one of the thrones. The lever won't be there until you trigger a certain Dark Brotherhood quest, but, when it appears, it reveals a room housing some rare Dark Brotherhood armor.
