Draw an image in the genre of Dark and Epic Fantasy. Visualize a subterranean maze-like tomb surrounded by ominous shadows and archaic traps. In the heart of this tomb floats a sinister skull with radiant, jewel-set eye sockets, known a demilich. This skull is encircled by a veil of dust and faint spectral figures, creating an atmosphere of foreboding. The tomb's walls are adorned with the skeletal remains of previous explorers, and the environment is saturated with a peculiar, ethereal, green radiance. A diverse group of adventurers, male and female, Caucasian, East Asian, African, and Hispanic, stealthily advance with expressions blending resolve and trepidation. The demilich stands on the verge of releasing a devastating scream capable of shattering souls. The scene exudes an overwhelming sense of looming catastrophe and a primeval, malign power.
