Uriel Septim V

Uriel Septim V was the seventeenth Emperor in Septim bloodline. He ascended the throne in 3E 268, after his father's death in the same year. His reign was marked by several ambiguous conquests, the most famous one being on the continent of Akavir. He's regarded by people as best warrior Emperor since his ancestor Tiber Septim.

History
Upon ascending to the throne of the Empire in 2E 268, Uriel V immediately turned opinions towards the potential power the Empire could wield. He was often away with his army, so the Elder Council controlled the Empire back home. He began planning invasions almost from the moment he ascended to the throne.

First invasion and heirs
His first invasion was to the land of Rosacrea. Next, was Cathnoquey, Yneslea and Esroniet. He conquered these land in roughly 13 years, but this wasn't the end. He finally invaded Akavir, the land which he planned to invade before all these. However, he was killed in the "Disaster at Ionith" in 3E 290.

His first son Uriel was born shortly after he embarked to Akavir and other children, the twins Morihatha Septim and Eloisa Septim about a month later.

Akaviri invasion
Uriel spent years amassing a massive naval force to attack Akavir. After the sailing across the Sea of Ghosts, his massive expedition began at earnest. After about two years into the campaign, he was killed at the Battle of Ionith. Despite his manner of death, he became known as the best warrior Emperor since Tiber Septim's time. His death forced the Imperial army to retreat back to Tamriel and Akavir was never visited by foreign army since then. When the news of his death reached Cyrodiil, Uriel Septim VI, only five years old, was crowned for next Emperor.
