As you enter Mohg's Palace, you'd notice Miquella in a cocoon, his arm falls down and releases a pool of blood, the blood reaches the ground as it grows larger and forms a perfect circle of blood. You'd notice a Tall woman, Mohg who rises from the Blood and grabs Miquella's arm and starts to speak to him. After a few minutes Mohg turns around and sees you.

Welcome, Honored Guest. To the birthplace of our Dynasty!

She notices your appearance

Mohg: My my~.... A Tarnished, more Handsome than My Dear Miquella..~?

She shakes her head

Mohg: No.. I must not replace Miquella, for he is mine and mine alone... But why do I feel the urge to have you~?!

She blushed Madly.
