The Eternal Champion is the hero and player character in The Elder Scrolls: Arena. As always, the 'Eternal Champion' is just a title given to the player; their true name is left to the creation of the person playing the game. The Eternal Champion helps rescue Uriel Septim VII from Oblivion after he was trapped there by the Imperial Battlemage Jagar Tharn.
Emperor Uriel Septim VII is summoned by the Imperial Battle Mage Jagar Tharn on rumors of treachery. Jagar Tharn betrays him and transports the Emperor into another dimension. Tharn's apprentice, Ria Silmane, witnesses his treachery and tries to warn the Elder Council but is killed by Tharn. After months of planning, Jagar Tharn transforms himself into the image of the Emperor and takes the throne. He summons demon minions and transforms them into the Emperor's Guard. He also sends a low ranking member of the emperor's court into the Imperial Dungeons to die. Ria Silmane becomes an incorporeal form through the use of magic and remains in this world so that she can warn the prisoner of Jagar Tharn's treachery and that the Emperor is actually Jagar Tharn in disguise. Ria creates a key for the prisoner to escape their cell so they can escape. The only way to stop Jagar Tharn is to obtain the Staff of Chaos, in which he holds his lifeforce, but the staff has been split by Tharn into 8 pieces and scattered across Tamriel. Since the prisoner is the only one that Ria Silmane could trust, it's up to them to reassemble the pieces and defeat Jager Tharn.
Finally, in 3E 399, after a long quest to reassemble the pieces which were hidden at the bottom of a dungeon in each province, Talin finally reassembles the Staff of Chaos. However, Jagar Tharn was not defeated like he and Ria Silmane had hoped. There was one final piece in the Imperial Palace, the jewel to the Staff, which would make it complete. The prisoner fought their way through the Imperial Palace until they reached the basement level, where they fought with Tharn. During the fight, the prisoner touched the staff to the jewel, melting Jagar. The staff creates a portal automatically to the dimension in which the Emperor and General Warhaft are being held. The Emperor then makes them the Eternal Champion as a reward for saving them and defeating Jagar Tharn.
The Eternal Champion's fate is left unknown at the end of Arena, however it is thought that they may have returned to their home province hailed as a great hero. Uriel Septim also claims that the hero will rule by his side, so the Eternal Champion may had been given some form of power over the empire after the events of the game.
- Although the Eternal Champion's name is created by the Player, the manual refers to them as Talin. If this is the Champion's official name, their family name, nickname, and title remain to be seen.
- Alduin's Wall in The Elder Scrolls V: Skyrim prophesised the events of Arena, showing Jagar destroying the Staff of Chaos that later resulted in the Eternal Champion's recovering of its pieces.
- Canonically, the Eternal Champion and the Hero of Daggerfall may be the same person. If this is true, then this marks the first time the player plays as the same character in any Elder Scrolls game.
