Originally named "Dungeon of Daggerfall: Battlespire," Battlespire was planned to be an expansion pack for The Elder Scrolls II: Daggerfall, but was later developed as a standalone game and released as a spin-off. It is the only game with the title An Elder Scrolls Legend. It was also the first Elder Scrolls game to feature a multiplayer option.

In Battlespire, the player takes the role of The Apprentice, who on the day of his final test in the training facility of the Battlemages, called the Battlespire, discovers that an army of Daedra led by Mehrunes Dagon has invaded and killed nearly everyone. On top of that, their partner has been held captive by Mehrunes Dagon himself. Over the course of seven levels, they must travel through various realms of Oblivion to reach Mehrunes Dagon, defeat him and escape back to Tamriel.
