In Navarro, there is Xarn, an intelligent deathclaws that Dr. Schreber is planning to have executed. The Chosen One can offer to take care of the deed for the doctor, and there are three ways to complete the quest.
- Kill Schreber, take the blue pass key from his desk, and free Xarn (1500 XP and 45 reputation).
- Kill Xarn (1200 XP).
- Fight the Enclave with Xarn (1500 XP).
The doctor might not fight after initiating combat, so the pass key can be taken without killing him. Alternatively, the door can be opened with any blue pass key found in the game.
The player should talk to the doctor to gain clearance to Xarn. Snookie guards the door to Xarn. The Chosen One needs to tell her that they have been cleared by Schreber to put down the deathclaw or kill her to be able to kill or free Xarn.
The third option is only available if the plan is to openly attack the Navarro troops. If the alarm has been raised when entering Xarn's room, he will ask them if they caused the commotion, and will offer to help them "kick some Enclave ass." This recruits Xarn as a temporary companion. When the Chosen One leaves Navarro, Xarn is considered free.
