Forged

Forged are a faction appearing in Fallout 4.

Background
The Forged are similar to Raiders, set apart only by their small numbers and fanatic obsession with the destructive power of fire. These enemies can only be found in and around the Saugus Ironworks, and they'll attack any and all trespassers on sight.

By accessing terminals spread throughout the building and if the sole survivor saves Jake in the bossroom one can learn the backstory about the Forged. Apparently the leader Slag came from outside the Commonwealth looking for recruits to form a new gang. Initially the process seemed to have been slow with many failing the gruesome initiation rituals. The number of recruits increased though after the Forged killed many of the notorious Gunners in combat.

Related Quests
The Forged are the raider faction that one will have to deal with in order to complete the Quest "Out of the Fire".

This quest can be started by speaking with Abraham Finch, who can be found in the settlement Finch Farm, a small settlement near the eastern coast. After speaking with Abraham, the Sole Survivor will be told that he and his family have been having problems with a nearby group of raiders known as "The Forged". Abraham will then share that his son, Jake, recently ran off to join them, and took the family's pre-war sword with him. The quest involves retrieving the sword, and if possible, Jake.

The Forged are based out of Saugus Ironworks, which just north of Finch Farm. Once having entered the main building and dispatched the numerous Forged equipped with melee weapons, molotov cocktails, and flamers, the player character will proceed to the Saugus Blast Furnace. After entering this small area, the Sole Surivor is greeted with a conversation between themselves, Abraham's son Jake, and Slag, the leader of the Forged.

During this conversation, Slag tries to convince Jake to kill a helpless settler in order to become one of the Forged. One has the options of trying to talk him out of it, encouraging him to do it, or deciding to kill everyone in the room. Any attempt to talk him into walking away or killing the settler requires a persuasion attempt.

After the ensuing combat is resolved, retrieve the Shishkebab from Slag's corpse and return to Finch's Farm, with Jake if he survived the battle, or without him if he sided against the Sole Survivor. If Jake survives, he will attempt to patch things up with his father. Abraham will be grateful to have his son back, despite being originally dismissive of him earlier, and will allow keeping the Shishkebab as a reward.
