History of Mantle of the Cormorant Blade

Overview

Mantle of the Cormorant Blade is a Legendary Warlock helmet. The lore line on the set is from Warlock Aunor Mahal on the Light being a skill rather than power or magic. This is the Warlock helmet of the set, paired with the Boots of the Cormorant Blade. It is a cosmetic-leaning armor piece with no named perk or god roll in the sources I used.

Acquisition

The Destiny 2 Wiki lists the Cormorant Blade Warlock armor (checked on the Duster, the set's chest piece) as a Season 6 item from Bright Engrams. The set is also offered as Warlock universal ornaments.
