Severus

Decanus Severus is the Legion's quartermaster at Cottonwood Cove in Fallout: New Vegas.

Background
Originally the leader of his own contubernium assigned to the Cove, Severus transitioned to the role of quartermaster when centurion Aurelius of Phoenix arrived in the cove. Beyond taking care of the stocks of equipment at the Cove and dealing with any captured gear, Severus also coordinates Legion patrols. The biggest problem is not the fact that the NCR avoids engagement with Legion raiding parties, particularly after the fall of Camp Searchlight, but the land mines the Army liberally peppers over the countryside to curtail Legion operations. The Legions has yet to develop a reliable method of disarming them.

The name impressed on him by Caesar is a popular historical name, bore by several emperors and notable persons in the history of Rome. 

Quests

 * Arizona Scavenger: After talking to Aurelius of Phoenix, the player can exchange NCR dogtags with Severus, either for 10 caps per tag and Legion fame or for equipment (which requires Barter 35 in dialogue with the Centurion). The optimal way to gain fame is to turn the tags in for caps, one at a time. 100 is enough to become Idolized.
 * The exchange rates are as follows. Note that asking to redeem for weapons and/or armor immediately removes five dogtags from the player's inventory, while food and ammunition have far less value than the 10 caps normally offered. All choices add fame as well.
 * Weapons:
 * 25 NCR dogtags → 9mm submachine gun or laser pistol
 * 30 NCR dogtags → 10mm submachine gun
 * 50 NCR dogtags → Laser rifle


 * Armor:
 * 20 NCR dogtags → Leather armor
 * 25 NCR dogtags → Leather armor, reinforced


 * Explosives:
 * 3 NCR dogtags → Frag grenade or dynamite

Other interactions

 * The player can also gain fame with Severus by two ways:
 * With 50 Explosives, they can teach the decanus how to disarm frag mines, by pressing the blinking yellow light.
 * With the powder charge schematics from NCRCF, found in cell block B, the player can show the Legion how to make more of them.

Bugs

 * The dialogue option "Do you see much action against the NCR?" clears the dialogue flag that disables the 50 Explosives skill check, enabling infinite experience and fame with the Legion.
