Colossal white cable tree filling an ancient stone cathedral chamber

a colossal white tree of branching cables and root-like filaments erupting from the floor of a massive ancient stone cathedral chamber, fanning upward into blinding light far above, twin monumental stone towers embedded with tiny glowing windows like an inner city flanking either side, a small group of robed cloaked figures standing in silent reverence at the base facing the structure, symmetrical low-angle vertical composition looking straight up, cool grey-blue monochrome palette, dramatic volumetric light shafts, epic scale, hyper-detailed CGI render, Octane render, cinematic architectural visualization.
