Nerus Sentia is a universal person in many universes in the gaming world. He's like Cid from Final Fantasy in a way, just manages to show up in any setting really. His name has existed in every Era of the Elder Scrolls series, several MMOs and even some simple games. In the world of Nirn, he is merely one who can control the fate of the people of Tamriel. Most of his incarnations are human, but some other races have been known to be called Nerus Sentia such as an Argonia and an Orsimer. For he does not choose a combat style of preferance and chooses to broaden the horizon by being whoever the hell he wants to be.
Nerus Sentia is a two part name with two meanings when put together:
nerus (nerr-us) n.- chaos, destruction, and shadows
sentia (sen-tee-a) n.- teacher, philosopher, and harbinger
