Kagrenzel

High Dwemer ruin north of Riften with a trapdoor orb that drops you down a huge shaft into a Falmer-haunted cavern lake, exiting via Stony Creek Cave.

Kagrenzel is a Dwemer ruin perched high in the Velothi Mountains near the eastern edge of the map, southeast of Mzulft and north of Riften. To get there, climb the steep path east of Ansilvund and keep going up a long series of stairs. It’s a short dungeon with one big gimmick: a glowing orb that sends you plunging down what is reportedly the longest survivable fall in the game, even longer than Bard’s Leap Summit.

What you’ll find

  • Frost trolls guarding the exterior, whatever your level.
  • A dark entrance hall with a pulsing orb on a podium, a couple of dead bandits and some urns.
  • Activate the orb and a circular cage closes around you, the orb circles beeping, and the floor opens into a long shaft ending in an underground lake ringed by waterfalls.
  • Leveled Falmer in the cavern below.
  • An Expert-locked Dwarven chest at the bottom of the lake, an invisibility potion nearby, two Falmer chests and an Adept-locked chest tucked between rocks by the bridge.
  • A single way out: an upward passage and bridge across the lake leading to Stony Creek Cave.

Quests

  • Ancient Technology (Dawnguard) – one of the places Sorine Jurard may send you for Dwemer crossbow schematics.
  • Family Heirloom – Vilkas may send you here to recover a noble family’s stolen valuable.
  • Shalidor’s Insights – Urag gro-Shub may send you here for Shalidor’s writings.

Notable items

  • A moonstone ore vein along the first path after the drop.
  • A centurion dynamo core hidden in the white water by a waterfall near the second Falmer chest.
  • A flawless diamond perched on an arch near the exit toward Stony Creek Cave.
  • Iron and corundum ore veins on the outdoor stairs southwest of the entrance.

Tips

Stand dead centre on the circular pedestal where the orb sat before the floor drops, and steer away from the walls on the way down – miss the middle and the fall can kill you. Clearing the urns and corpses with Unrelenting Force first helps, and Become Ethereal timed as the floor opens usually guarantees a soft landing. For the diamond, Telekinesis, an arrow or a Shout will knock it down.

Don’t try to sneak in backwards through Stony Creek Cave: you won’t reach the main hall that way.

Good to know

An unmarked hunters’ camp on the slopes nearby holds the Archery skill book Father of the Niben. During the fall you can also glimpse enormous skeletal shapes in the shaft walls – bigger than any creature in the game.
