Rocksalt

 is a Raider in Tepid Sewers, it appears that she is not relevant to any missions or quests in the game itself.

Although there is no given story it seems that Rocksalt is the leader of a small sect of Raiders living in a mole rat infested sewer. Rocksalt drops Rocksalt's key which opens a safe, ammunition box, and a number of other small toolboxes.

Rocksalt's gender and appearance appear to be determined randomly. ps: Rocksalt is enslaveable. does need to be mezzed twice, and will remain hostile.

Apperances
