Secrets of the Illithid Tombs

Publisher's blurb:

The silence filling the subterranean streets of K’Jeek is absolute. No footsteps echo along the dust-covered streets, no cries from the deserted prisons of the slave pens. The great Temple of Ilsensine, once thronged with devotees, lies mute. Suddenly, inside the darkened temple, a gout of green flame lashes out through the darkness. A cry, ear-piercing in the vast silence, shakes dust from the dome of the ceiling far above. As the flames recede, they reveal a humanoid skull. The grinning visage, cackling maniacally, begins circling what was once the main sanctuary. The streets of K’Jeek are silent no more.
