Miles Accisius is a Centurion within the Legion. Patrolling along the Colorado alongside his force of about seven, including him, they happened to spot a group of NCR entering Vault 24. Deciding to bring himself merit by destroying a possible LRRP, he launches an ambush against them. It was successful in the beginning, and they took down a good number of NCR. But much to his displeasure a group of BOS Knights and Paladins ensnare both sides within the Vault. Understanding the grave situation but refusing to surrender, Miles Accisius orders his troops to fight back. Taking heavy losses, he and the remaining Legionnaires lock themselves into a room to await an attack..

Miles Accisius is your typical Caesar Legionnaire. Disapproving of the weak, idolizing the strong. However, he shows that he possesses a great deal of tact, understanding that utter annihilation is good for no one and eagerly awaits, at a choke-point created by himself, for the BOS to attempt to destroy him and his remaining Legionnaires. He is gruff, eager to fight, and untrusting of any proposition.
