Zytera from "Forbidden Lands" TTRPG/ Model by Observer Tree Studio.

"They say that the sorcerer Zygofer, during the final battle of the Fourth Alder War, summoned a demonic horde that slaughtered King Algarod and the Alderlander army. To consolidate the alliance, Zygofer and his daughter, Therania, agreed to being merged with a demon prince to form the man-spider Zytera, whom the Rust Brothers still venerate as the prophet of the god Rust. Allegedly, Zytera still rules the holdfast of Vond, from which the monstrosity sends out the unnatural demonic creatures that haunt the Forbidden Lands."
