At an indeterminate time, Silmane once became the apprentice to Jagar Tharn, then-head of the ruling body of Tamriel: the Elder Council. After the End of Harvest festival that year, Tharn asked the council for relieve of his duties, secretly to plan his coup of the throne, claiming he wished to study other circles of magic. He then advocated his apprentice, Ria Silmane, to resume his duties as Imperial Battlemage of the Empire, and head of the Elder Council. The council fully approved.
Jagar Tharn returned, and usurped all Imperial power in 3E 389. Silmane attempted to warn the Elder Council of his treachery. Before she could, however, Tharn used the Staff of Chaos and destroyed her corporeal form.
Using her powers as a sorceress, she fought the pull of the afterlife. She instead appeared to the Eternal Champion in the Imperial sewers, as an incorporeal spirit. She would have gone to the Elder Council instead, but that would have taken far too much of her energy to appear to so many.
She told the Champion of Tharn's betrayal. She then used magic to connect herself to them, so that she may appear in their dreams, and freed them from the cell—setting them free to obtain the eight shattered pieces of the Staff of Chaos.
The more she used her powers after that, the shorter she could remain in the world, so every encounter with the Champion became shorter and shorter. In 3E 399, the Eternal Champion finally obtained all eight pieces of the Staff of Chaos. Ria Silmane then sacrificed what little energy she had left to cast an Illusion spell, changing the Champion's appearance so they may infiltrate the Imperial palace undetected. She then ascended to the afterlife.
- It is written, and Silmane herself states that Silmane was executed by Tharn with the Staff of Chaos, while in-game he is depicted as killing her with some sort of spell with his hand.
