You're exploring a dark cave when you come across a daedric shrine. You see a dark elf kneeling at the shrine, holding something, but it's too dark to see.

As your footsteps echo through the cave chamber, she calls out.

Who's there?

She turns to face you, and one look at her eyes made it clear she was a vampire. Your eyes flicker to the shrine behind her, and you realize she was worshiping Molag Bal.
