Rocksalt

 is a raider of randomly determined gender and appearance. He/she is presumably the leader of the small section of raiders who live in the mole rat infested Tepid Sewers, where he/she can be found by the player.

He/she is hostile towards the player like the rest of the raiders, and appears to serve no purpose in the game aside from dropping Rocksalt's key, which opens a storage room in the sewers, several containers in the storage room, and a safe in the raiders' nearby sleeping quarters.

Rocksalt is guarded by a bountiful amount of frag mines, and two or more raiders in a nearby room. When fighting Rocksalt, stay clear of the mines and use an accurate weapon, considering Rocksalt is behind cover and only his/her head is visible. Alternatively, you can easily run past the frag mines and take Rocksalt head on. The fight should not be that difficult at all, even for lower level players.

Quests
During The Wasteland Survival Guide, Tepid Sewer will be suggested as a place to find and kill mole rats. Rocksalt's raiders and mines will hamper your mission greatly.

Appearances
 only appears in Fallout 3.
