The dean is approximately similar in rank to the NCR Sergeant, and from the very beginning he is the head of the contour beria - a unit of ten people. He is already a proven veteran, who was raised in the Legion almost from his very birth, where discipline, as well as the philosophy of the Legion, was hammered into his head. But due to the limitations of teachers, this very philosophy was hammered in by a limited tribal understanding, in the end it turned out to be extremely far from the ideas of Caesar himself.
From the training camp, the newly created dean is sent to Flagstaff, a beautiful city reborn in almost pre-war splendor, for this was Caesar's desire - to have an island of civilization in the middle of wild Arizona, for which the Legion fights. Here he, instead of with his detachment, essentially by accident, stumbles upon an attempt to assassinate Caesar and prevents it, for which Caesar himself invites him to join the Praetorians at an audience. But here the hero does what others did not dare to - he refuses. Arguing this either by the fact that he wants to stay with his people, with his new tribe, considering himself unworthy to stand next to the son of Mars. Or that his service on the front line will be more effective for the Legion, and what happened is nothing more than an accident. In any case, Caesar, with courage, will praise the player and fulfill the request by sending him to the front, against the Kosoplyos tribe.
There the player will take part in hostilities against the rebellious cohort. Together with his contourbery, he will be able to go to the rear of the cohort and divert their attention so that their orders were broken, and the bulk of the legionnaires were able to defeat the rebels. He is again offered a promotion, but he refuses. However, having learned about everything that happened, Caesar in Flagstaff decides to send this century to Phoenix. He knows that the rebellious cohort is only part of the rebellious century, and part of it has dug in southwestern Phoenix.
In Phoenix itself, the player's contouring is mistakenly sent to lead the first attack, to become cannon fodder that will blunt the enemy's gladius. But instead, he manages to save the orders of the first line of attack and break the enemy. And upon returning to the camp, he discovers that the Frumentarian has executed the centurion responsible for the attack, although he does not know what the matter is.
Meanwhile, the player's contour is transferred first to the Arizona Rangers, next to which is the last part of the rebellious maniple. And he not only defeats the enemy, but also deserves a decision - how to deal with the captured rangers. He either executes them, or orders them to be released, arguing that by letting them regain their strength and prepare for a new battle, the Legion will receive a new test that will temper it and only make it stronger.
In the same way, he is sent to California, where the assistant to the military tribune, who led the cohort, and now joined Bratst Steel, is hiding. And if he takes the assistant with him, then he will have to solve a similar issue with the Brotherhood. And in both cases, after completing the task, you can find out that the player is being watched by the Frumentarii.
In any case, traces of the military tribune itself lead to the Hub, and there the dean will lead the night attack on the mayor's building, where the military tribune is hiding, giving information about the legion's tactics by the rangers of the New California Republic. He will execute him in any case, but with different motives. Whether it is the desire to kill the betrayed "god", or to put an end to the coward who refused to serve the idea that should bring peace to the Wasteland.
Either way, the player is greeted by the Frumentarians and reported that Caesar himself ordered him to join the forces in the Mojave. No, not as a centurion, for Caesar himself respects the player's decision to stay with his people. He was given a much more dangerous and honorable role - to go in the vanguard of the attack on the Hoover Dam.
