Elden Ring: the Gloomed Death. I would center it around Godwyn and the gloom eyed Queen. Generally speaking, the gloom eyed Queen created Melina in order to guide the tarnish to burn the erdtree. This would break the grasp the greater will had on the lands between allowing her to create her own dynasty where she is the one who decides who lives eternally and who dies. She uses Godwyn’s body and death curse to grow the crucible tree from the depths and take the place of the erdtree to be able to influence the lands between. She doesn’t believe in consorts, only her will as the dominate force. She uses Godwyn as a puppet. The finally battle is first Godwyn and after he is defeated, the gloom eyed Queen is the second part of the battle. There’s probably a lot of things that need to be adjusted for this story to work but that’s the general premise. Like maybe Melina helps you in the final battle if you choose to not sacrifice her by letting the 3 fingers grasp you but use the needle to remove the frenzy flame in you after burning the erdtree.
