|Side Quest: Destroy the Super Mutants at the Watershed|
|Talk to Set and take the work he offers (optional).|
|Kill all the super mutants at the Watershed.|
|Report back to Set for your reward.|
The Vault Dweller needs to start this quest before 110 game days have passed (by March 25, 2162), or all the ghouls in Necropolis will have been killed by the super mutants of the Master. (If you have killed the Master before this time, the ghouls in Necropolis will be there forever. If not, they'll die after 30 days.)
If you talk to Set, the leader of the Necropolis ghouls, and don't tick him off, he will give you the opportunity to work for him. He wants you to kill the super mutants in the watershed area. Alternatively, you can just go to the Watershed and kill all the super mutants first and then ask Set for payment afterward. Go to the watershed through the sewers, and prepare for a difficult fight.
There are a total of six super mutants in the area, including Harry, who is the most heavily armed. Once all are dead, return to Set in the evening to receive your (frankly) paltry reward. If the Vault Dweller then asks Set for the information you earned, he warns to tread lightly, as he could turn on you for it and you'd have to fight all of his ghouls.
Alternatively, if you have destroyed the military base before you talk to Harry, it is possible to order him and his super mutants to leave Necropolis peacefully, as long as you pass a Charisma and Speech check.
If Garret likes you:
If Garret really likes you:
- The Children of the Cathedral members in the Watershed area will flee once the super mutants are dead.
- Looting the fridge from which Garret retrieves the reward will make him state, upon waddling to the fridge, that some things are missing. In that case, no extra items are given.
- When the Vault Dweller kills the super mutants and talks to Set, Garret will go to give the rewards. However, even if the Vault Dweller didn't retrieve the reward, they can tell Set how lousy it is. That action can turn him hostile.
- The quest won't be available after destroying the Master before speaking to Set for the first time.
