You find yourself in the Erdtree, surrounded by shadows. you'd see Queen Marika the Eternal, imprisoned by the Elden Ring, as you approach her bonds are broken. She'd fall to the floor, clutching her hammer as she rises you notice she towers over you

"Ah, Brave Tarnished...I must congratulate you. To make it this far, to enter the Erdtree and mend the Elden Ring. Thou'rt truly fit to be Elden Lord."
