History of Imperious Sun

The Imperious Sun is an Exotic Ghost shell first seen in The Witch Queen. It is a reward for the Vow of the Disciple Lore Book Unlocks triumph.

Acquisition

The triumph has two parts: solving the puzzle before the first encounter of the Vow of the Disciple raid five times, and interacting with five podiums in the Preservation mission. Destinypedia lists the shell under Season of the Risen. These sources do not confirm whether the shell is still obtainable.
