They decided you weren't the Nerevarine. Why? "To fulfill the prophecy, I followed a path of blood and war. In the end, my path became a road that led to nowhere and I was cast down from my lofty spot. Take my scroll and help the Wise Woman understand the futility of a senseless war."
Chodala has announced himself as Nerevarine, and with his ideas, this action may lead to war. The Vestige is tasked with stopping this potential war by disproving Chodala's claim by speaking with the failed incarnates of Indoril Nerevar, Incarnate Aduri being one of them.
- The location of Aduri's body is very close to that of Peakstar's in The Elder Scrolls III: Morrowind. This may be a reference to Aduri's past.
