Fallout: The Traveler/Traveler Origins

Traveler Origins are premade characters. Chosen during character creation part of the quest An Alluded Concussion, each of the eight Traveler Origins comes with a predefined backstory, as well as its own interactions, but all of them, as players and companions, are wildcards. Each Traveler Origin character is a unique experience with a unique quest and dialogue.

All eight Traveler origins will be available in-game as as potential companions who can join the chosen Traveler's party.

Overview
Most origins also have a set background, race and appearance that cannot be changed.

For a fully customisable character, the Custom Traveler origin is also available in the An Alluded Concussion quest.

Trivia

 * The Traveler Origins are based off the mechanic of the same name from Baldur's Gate 3 and the premade characters from Fallout 1 and Fallout 2.
