Basadid was anointed Sun-King after his brother Iriv's untimely disappearance. In response to Iriv's demise, Basadid ordered the construction of Sunfall at the Sundom's western edge, and a garrison at Blazon Arch. Basadid chose to have the Sunfall fortress built atop an ancient ruin, believing that it held some strategic value.
To discourage further expeditions into the west, Basadid deemed the land west of Sunfall the Forbidden West, where only the Sun may go.
Basadid was succeeded by the Radiant Khuvadin.
