Frostflow Abyss

Investigate the murders at Frostflow Lighthouse, descend into the Falmer and chaurus nest below it and lay the keeper Habd to rest.

Frostflow Lighthouse on the coast of Winterhold Hold should be a cosy family home. Instead you find blood, bodies and a cellar that has broken through into a cave full of Falmer and chaurus. Nobody gives you this quest; the lighthouse journals do, and they lead you down into the Abyss to find out what happened to Habd and his family.

How to start

  • Enter Frostflow Lighthouse and walk into the central room. The quest starts there.
  • Do this before going down to the basement; entering the cellar first can break the quest.
  • Be warned that Falmer and a large chaurus reaper wait below. Low-level characters may prefer a careful sneak-and-archery approach.

Walkthrough

1. Search the lighthouse

Read the journals scattered around the ransacked house for clues. Sudi’s journal points to the cellar key: it is inside a burial urn on the mantel above the fireplace. Unlock the cellar and go down carefully, as there are bear traps on the steps. Kill the chaurus in the cellar and head through the opening in the far wall.

2. Into Frostflow Abyss

The first cave chamber holds Falmer and chaurus; once they are dead, search it to find the remains of Mani. Push on to the next chamber, which has Falmer huts and a fenced pen. The body of Sudi lies there with a Scrawled Page and a Bloodstained Note that fill in the family’s fate.

3. The chaurus nest

Keep going, killing or sneaking past chaurus, until you reach a hole in the floor. Drop down onto the ledge below and clear the chaurus there. This area is a nest, and you can harvest chaurus eggs by the hundred if you like.

4. The chaurus reaper

A large cavern full of stalactites holds several chaurus and an unusually big chaurus reaper, guarded by at least one more chaurus. The reaper must die before you can leave, and it can be tough at low level. Its body holds Habd’s remains and Habd’s lighthouse key.

5. Habd’s last request

With the remains in your pack, follow the trail up along a ledge back towards the Abyss entrance; there is a Falmer chest on the way. Where the path seems to end, jump down into the first cave chamber. Return to the lighthouse cellar and go upstairs (the bear trap on the steps has reset). Pick the lock on the other wooden door, climb to the top of the lighthouse and up the ladder to the fire pot. Activate the fire to lay Habd’s remains to rest and receive Sailor’s Repose. Finally, open the chest on the roof with Habd’s lighthouse key to complete the quest.

Rewards

  • Sailor’s Repose: healing spells restore 10% more.
  • The contents of the rooftop chest and the Falmer chest.
  • As many chaurus eggs as you care to carry.

Tips and notes

  • A Torchbug in a Jar sits on the lighthouse mantel, and the Restoration skill book Mystery of Talara, Book II is on a dresser in a northern room.
  • The source is contradictory about clearing the Abyss before starting the quest: one note says the quest then cannot be finished, another says you can still burn the remains and get Sailor’s Repose. Start the quest in the central room first to be safe.
  • Hob’s Fall Cave from Pantea’s Flute is nearby, so both can be done in one trip.

Choices & consequences

Known bugs & fixes

If Frostflow Abyss is cleared before the quest starts, the quest may become impossible to finish. Entering the basement before the central room can bug the quest.

Lore notes

Sudi’s scrawled page says her father came down to find them and was captured too; the family was taken into the Abyss by the Falmer.
