Rimerock Burrow is a small cave located at the northwestern edge of Skyrim.
The interior of Rimerock Burrow
The sole occupant of this cave is a powerful mage Sebastian Lort, who can summon leveled atronachs and wield exceedingly powerful lightning spells. There are a few stray ingredients and a copy of the Conjuration skill book 2920, Hearth Fire, v9 in the small back bedroom. If sent here by Clavicus Vile, The Rueful Axe will be laying on the large slab next to the arcane enchanter.
