The Legion as they sneak into the abandon town to retrieve the Watcher's arm.
Silvermines is an abandon mining town placed at the base of the Cloudspine Mountains near Seven Gates, right under the shadow of Tharsis. This was where the Watcher was imprisoned during the final years of the Wind Age.
The Legion would return to this town in November 19, 2480 AE during the Great War to search for the severed arm of the Watcher. They were contested by the Deceiver, who was also searching for it. Despite dark forces lurking about in the mines, the Light were successful in their mission. This led to a battle upon the northern foothills of the Cloudspine on November 30, where the Legion had to fend off the Dark from taking the arm.
