The Cottonwood Cove HQ is a small stone building with two stories, connected by exterior stairs. The lower story's main room appears to be a communications and storage room. The upper story serves as the office and living quarters of Aurelius of Phoenix.
- Legion raid plans - In one of the HQ's filing cabinets on the ground floor
- Legion patrol notes - In the Aurelius of Phoenix's desk
- Recompense of the Fallen - In the same desk
- Grognak the Barbarian - In the cubby hole of Aurelius' night stand
At night, the office of Aurelius of Phoenix will be marked as owned. During the day, or when Aurelius of Phoenix is not in the office, but outside on the balcony, it will be marked as unowned. This also applies to the lower part of the building, which is inhabited by Decanus Severus at night.
Cottonwood Cove HQ appears only in Fallout: New Vegas.
