The 85ish year-old emperor of Tamriel. He has been the protagonist of all 4 ES episodes, but in the 4th chapter he will perish in the start of the game, by hands of the unknown assassins who will raid the palace. In his dying breath, he will ask you to find his long-lost son and will hand you the Amulet of the Kings, the heirloom of the royal crown.

No one knows who he is or from where he comes from. Some claim that the Heir is in fact Callaxes, who was exiled during Jagar Tharns rule, but alas, he is the last living son of Uriel Septim and the only hope that Tamriel has to escape the nearing end of the Daedric invasion. He will be a valuable ally in the final moment of the Main Quest.

The leader of the Mythic Dawn Cult and final boss of the storyline. He is responsible for the emperors death and the Daedric invasion. It was him who had slain the emperor bellow the palace dungeons and escaped the guard unharmed on the orders of his master, the Daedric god Mehrunes Dagon. Little is know about the Dark Priest, except that he comes from a line of distant kings (possibly ayleidic).

 

One of Mehrunes Dagons strongest lieutenants, he lead the assault on Kvacth and is responsible for the towns destruction. Arrogant and ignorant like most Dremora nobles, he looks at mortal life with disgust and hatred. He is amongst the first Daedra to die.
