Karliah

Karliah is a Dunmer Marksman in Skyrim. As a former member of the Thieves Guild, she serves as a member of the Nightingales.

Background
She was trained under, and was involved romantically with, Gallus Desidenius, and was a former partner in the Thieves Guild with Mercer Frey. Karliah was exiled from the Thieves Guild for 25 years after Mercer Frey framed her for the murder of Gallus Desidenius.Gallus called her "My Nightingale"

The Nightingales Vol. 2 suggests that Karliah is a distant descendent of Queen Barenziah.

Speaking with Silence
Mercer Frey and the Dragonborn hunt for Karliah in the cave Scoundrel's Folly.

Once Mercer picks the Dragon Claw door, the Dragonborn walks in first. Karliah shoots the Dragonborn, who is poisoned and passes. Awakening again, their vision is blurry. Mercer and Karliah are heard talking. From their dialogue, it is learned that Mercer is guilty of committing many crimes against the Guild. Karliah escapes and Mercer notices the Dragonborn is still alive. Enraged, he stabs the Dragonborn, attempting to kill them. Karliah and the Dragonborn then head to Winterhold to figure out how to decode Gallus' Journal.

Later interactions
Karliah assists the Dragonborn in some of the later quests of the Thieves Guild questline, most notably helping recover the Skeleton Key and the Eyes of the Falmer.
