"An alien bio-factory called "Nesthold", specialized in producing organic tissue. The building looks like a massive chitinous nest or layered dome structure, built from smooth carapace-like materials. Its form suggests biological assembly, like insect hives or layered cocoons. No leaves, branches, or fine plant elements. Some glowing cracks or tissue channels may be visible. Clean geometry with rounded, massive shapes — perfect for low-poly use.
