Cinematic low-angle shot, photorealistic 8k, 16:9. Inside a dark underground arena, a metal trapdoor grinds open in the sandy floor. From the black void below, enormous pale segmented worms emerge slowly — thick as tree trunks, blind, glistening with mucus, ringed bodies stretching three meters long. Their circular mouths with rows of tiny teeth probe the air. Sand cascades off their bodies as they rise. Harsh overhead torchlight illuminates the slime on their skin, creating grotesque reflections. The arena floor stretches around them, empty and ominous.
