Broken Helm Hollow (Skyrim)

Broken Helm Hollow is a very small cave located south east side of the mountain south east of Riften The entrance is to the left of a large waterfall that is the location of one of the various treasure chests associated with looted treasure maps. There are two Silver Hand guards outside with another three along with their leader within. The location is important as part of the Companions Questline wherein you must aquire a piece of the legendary axe displayed in the Companions Headquarters. The chest containing the actual piece is boobytrapped with a swing mace so be sure to stand away when opening the chest. There is a pullchain near the rear of the cave that opens a passage to a torture room of sorts where you will find a corpse of a named NPC and be given the quest to inform his family of his demise.
