Outcasts and Remnants - Quest Mod Plus Mod
MODApr '17 Mod of the Month runner-up. 20 hours of game play with new factions, locations, player bases, and fully-voiced custom companions.
For immersion and game-play difficulty purposes, you should first complete the main Fallout 4 quest "Reunions", where you confront Kellogg at Fort Hagen, after which the first quest in this mod, "Initiation", should start automatically the next time you change locations.
Check out Murdering Chainsaw (requires Automatron DLC) if you want to give Ash a better melee weapon than the modified Ripper he initially has.
