Katja

 was a scavenger living in the LA Boneyard, around 2161.

Background
Katja was a Scavenger, occasionally camping out with the Followers of the Apocalypse, even though she doesn't follow their way of life. She hates dogs and will express this disdain out loud every time the player examines/pets Dogmeat.

Interactions with the player character
Katja is a recruitable NPC located in the Boneyard. This can be done by just asking her... simple.

However, it is hinted that the Vault Dweller never even met her as she is not mentioned at all in his memoirs.
