Fallout London 17 - Breaking The Cycle
One of the better possible outcomes for the Vagabond-Syndicate war. The Wayfarer becomes the new leader of the Vagabonds and brokers a peace treaty and ensures both sides end their fighting for the time being. This outcome is dependent on how much you have earned the trust of the other Vagabond lieutenants throughout the Vagabond questline.
The perk gained at the end of this path is also quite good (Piper's affinity perk in vanilla Fallout 4). However, if you are not Intelligent enough, you will need to fight Gaunt in a 1 on 1 duel for the fate of the Vagabonds, and he's not easy to defeat.
