Elden beast?

The Elden Beast is a mysterious creature whose motives remain enigmatic, but based on its position, it can be assumed that it is fulfilling its role as the physical incarnate of order. As such, it presumably punished Marika for her actions in shattering the Elden Ring and ensures she remains imprisoned in the Erdtree by possibly mutilating her body and keeping her crucified. It also ensures that the Tarnished does not become Elden Lord, regardless of their intentions.

The Elden Beast's actions suggest that it is willing to let the Lands Between be left forever in disarray instead of relinquishing control to the Tarnished. While it does not speak, it does appear that the Elden Beast is in fact an intelligent being, in terms of combat.

Long ago, the Greater Will sent a golden star bearing a beast into the Lands Between, which would later become the Elden Ring. It was the vassal beast of the Greater Will and the living incarnation of the concept of Order. Marika, a Numen Empyrean, would became a goddess and the vessel of the Elden Ring and would establish the Golden Order and rule over the Lands Between as the one true god. However, Marika would eventually shatter the Elden Ring, leading to her imprisonment inside the Erdtree.

After untold hardships, a Tarnished champion fights their way into the Erdtree where they find the shackled Marika, and face Radagon, Marika's male "other self" and the reigning Elden Lord, the two of them sharing the same body. After his defeat, the Elden Beast emerges from Radagon, transforming Radagon's defeated body into a large sword, and faces the Tarnished.

The Elden Beast is the main antagonist and the final boss of the 2022 action-RPG video game, Elden Ring. It is a divine being that resides within the Erdtree and acts as the last threat that the Tarnished must face before they could claim their title as Elden Lord.

As the vassal of the Greater Will, the Elden Beast is the pure embodiment and living incarnation of the Golden Order. As such, it is considered to be the true ruler of the Lands Between.

Appearance: The Elden Beast is a large creature with a transparent body. Its inners consist of bright dots and golden veins, resembling the branches of the Erdtree. Its head is featureless although it does possess a bright light in the center of the head, presumably an eye. It has long humanoid hands and eight wings protruding down its back. Its lower body is hidden in the water but can be seen when the beast takes flight. It has long legs and a tail that ends with the golden veins protruding out in the shape of roots. This version of Elden beast however has a more feminine human look. So it actually has a humanoid face and head instead of its normal featureless head. This version of Elden beast also has long golden hair. The Elden beast is eighty five feet tall from tail to head.
