Katja

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

Background
Katja is a scavenger from Adytum who occasionally camps 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.

Other Interactions
Katja is a recruitable NPC located in the Los Angeles Public Library. She can be recruited simply by being asked to join the player. Afterwards, she can be used to lockpick closed doors. She is also a decent shot with any large handgun (sprite limitations prohibit her from using regular pistols).

She has 39 hit points.

She will turn hostile if the player killed people in Shady Sands before recruiting her.
