1000x1000+ Minecraft sci-fi boss arena. 700-diameter circular netherite platform floating in dark void. Floor has concentric rings of deeply carved glowing enchantment table runes illuminated by cyan sub-lights. Background filled with dozens of massive, towering 3D double-helix DNA structures floating in the sky. Floating DNA strands are built from semi-transparent gray glass with glowing light-blue nodes. Ethereal, grand, ominous atmosphere, intricate geometric block carving, hyper-detailed.
