Vanech was a Breton Arch-Priest of Kynareth in 3E 402. When the kingdoms of Sentinel and Daggerfall went to war over who was to control Betony Island in the Iliac Bay, he considered the island a holy realm of Kynareth and refused to cede it to Hammerfell. At the negotiations between the High Rock city-state Reich Gradkeep agreed to meditate between Lysandus of Daggerfall and Camaron of Sentinel, Vanech submitted a fake treaty which made Camaron upset and eventually plunged the city-state into chaos. The fake treaty that Vanech signed led to total war between Daggerfall and Sentinel.
