This group is a resurrection of the original raiders of Appalachia, after the original groups were wiped out by the Scorched. After these raiders, composed of survivors of the original groups who fled Appalachia and new members picked up along the way, caught wind that people were returning to the land they once claimed for themselves, they and their leader Meg decided to come back and put a stop to anyone who would take their territory.
They set up a formidable base of operations at the crashed space station, which they renamed the Crater. It is inevitable that outsiders who drop by unannounced will not receive a warm welcome.
Several smaller groups unrelated to the Crater faction also entered Appalachia at the same time as them, leading to tense interactions between their members, if not open hostilities. Most notable among these groups are the Blood Eagles, whose violence and sadism has led to their being declared monsters by many of the Crater raiders. Other groups include the Free Radicals, Edwin's gang, and Sargento's gang.
After deciding whether to kill him or allow him to go out on his own terms, the residents return to tell Meg what happened, and she agrees to have the raiders inoculated to protect them from the Scorched Plague. With the raiders now safe from becoming more of the scorchbeast queen's minions, the residents soon have to decide which faction they are going to join to get to the riches hidden within Vault 79, as they can either join Meg and the raiders or go against them by allying with Paige and the Settlers. This will affect the residents' relationship with the two factions depending on their actions from then on.
Various raider patrols may be randomly encountered throughout Appalachia fighting off threats such as super mutants, Scorched, or feral ghouls. Should the residents choose to help them, they may speak to them afterward and receive a small boost in reputation with the raiders, but only once Strange Bedfellows is completed, making the Raiders non-hostile to the residents after getting in Meg's good graces.
Raider scavvers are members of the Crater group searching for good materials to take advantage of in Appalachia. They may appear in random encounters of roaming raider bands battling various creatures.
Raider hunters are employed by Rocksy to hunt down former raiders during the daily questRetirement Plan. Several options in conversation include asking for their help dealing with the former raider, convincing them to go cause trouble with the Settlers, or telling them to give up the search and let the player character handle it.
Raider thieves have the assigned duty to steal from unsuspecting groups, such as the Settlers. They player character may have to negotiate or kill a raider thief during the daily quest Vital Equipment.
