Severus is a Roman Centurion in Ryse: Son of Rome. Severus fights during the barbarian invasion of Rome. It is unclear which Legion he is apart of. He is a very minor character, but plays a major role in the final stage of the story line.
After Commander Vitallion is slain by Boudica and the barbarian horde breaks through the Roman defenses and spreads throughout the city, Severus finds General Marius before a statue of the first Emperor Augustus Caesar and reports to him that he is unsure how long the Roman lines can hold. Just then, a gust of heavy wind blows through, and Marius interprets this as a summons from the gods. Severus realizes this as well, but states that the gods do not favor them and is about to recommend they retreat when Marius interrupts and scolds him. Severus kneels before the general in respect and Marius swears to him that Rome will not fall, then orders him to organize the remaining forces.
Severus regroups with Marius some time after the general has slain Boudica, and they fight their way to the palace causeway where Marius hears the Emperor Nero calling out for the Legionaries to defend him. Marius then hands off a blood soaked sack containing Boudica's severed head to Severus, and tells him "Display this in the highest place you can find. When the barbarians see it they'll run. The battle will be ours." Severus departs to carry out his order while Marius moves to rally the palace defenders, and is never seen again. The Centurion succeeds in his task, resulting in the barbarian horde retreating when they learn of Boudica's demise.
- Severus is the only Centurion in the game other than Marius who is distinguished by name.
- The name Severus actually originated as a family name during the time of ancient Rome, and was not a commonplace given name.
