Tiber Septim is the name he took after becoming emperor; his real name is Hjalti Early-Beard, which sounds somewhat nordic. He was born in Alcaire, which is in Highrock.

His least likely race(besides any race that is non-human or redguard) is Imperial; his real name suggests he was a Nord, his native birthland suggests he was a Breton. His having been raised in a different kingdom should have nothing to do with his race.
