Legate Lanius

Lanius is Caesar's Legate, living in Legate's Camp in 2281. He is the final boss of Fallout: New Vegas.

Background
Asking Caesar about the legate reveals that Lanius was a member of a tribe hostile to Caesar's Legion. Lanius was the bloodthirsty champion of that tribe, sometimes ambushing whole groups of legionaires by himself. When Caesar's legion tracked down his tribe, they knew that they wouldn't be able to win so chose to surrender. This act drove Lanius into a blood frenzy; killing the Chieftain and 15 others of his own tribe single handedly before he was brought down. When Lanius woke up most of his face was torn off and Caesar was standing beside him. He offered Lanius a place in the Legion and a mask forged especially for him. Lanius accepted.

Quests
If siding with Legion, Legate Lanius will be the one who gives the final order to the Courier, and also the one who congratulates him after the battle. In all other cases, Lanius is the final opponent.

At the battle of Hoover Dam, if against the Legion, Lanius can be convinced into surrendering with numerous Barter and Speech checks, respectively 55, 65, 75, 85 and 100. Convincing him that the vast territory of the NCR is its weakness and that the Legion will not be able to claim and hold it. It is also possible to take a different speech angle to convince him to leave, suggesting that his fight was too easy because a trap lies in wait for him, and that you are only telling him this because it would be dishonorable to defeat a foe in such a way.

Appearances
Lanius appears in Fallout: New Vegas.
