Halldir's Cairn is a cave players are sent to during the quest, "Find Runils Journal" or "Find Rjorn's Drum" (Bard Quest). Even without a quest, alchemists may find this dungeon useful, with the first (non-combat) room holding a large number of mushrooms (White Caps, Namira's Rot, Imp Stools, Fly Amanita, and Bleeding Crown), approximately 40 or so in total. Some low-level armor and weapons can be looted from three deceased bandits in the room. On a pillar is a journal telling of a ghostly voice compelling the bandits to kill themselves on a blood-soaked rock cairn as well as a key to the only door going further in.
There is a puzzle room at one point, where players must turn three rocks to match the symbols on the walls opposite them, and then pull a lever to advance to the next room. Incorrect combinations result in a dart trap shooting darts at the player when the lever is pulled.
The correct combination is bird, snake, fish, when going clockwise around the puzzle, starting from the lever.
The final room is a fight against Halldir. He is a mage, who will summon copies of himself when damaged. They, and he, will attack with destruction school spells. The door to the room locks behind the player when the fight begins.
Notable loot includes a Spell Tome of Raise Undead (may be leveled), some nice armor and weapons at higher levels, and numerous soul gems.
Halldir drops an Ancient Nord Sword of the Cold, some gold and Halldir's staff, which has a 60 second Calm (works on creatures and people lower level than the Dragonborn) and Soul Trap effect.
