Sealing the Blade
Defeat Adleg, Warden of Oryx, and then Alak-Hul, the Darkblade, within 30 seconds to seal your Sol Edge.
"The Wardens you seek are infamous devourers of the Light. Each has its own heinous preference. Together, they guard the Sunless Cell, where Alak-Hul, the Darkblade, languishes." —Eris Morn
