Exile Baroness
From Destinypedia, the Destiny wiki
Exile Baroness was a Fallen Baron from the House of Exile mentioned in the Ghost Fragment: Fallen Grimoire.
She once fought alongside Cayde-6 against the Hive and later die by his hands. Cayde would continue to remember her by holding onto a House of Exile Banner marking the Baroness found in his treasure chest and retell the Baronesses story at the end of Nightstalker quest.
