Here is the legend (as garbled, embellished and incomplete as most such legends, but helpful nonetheless) recited by Glib, as a result of the Ring of Wishes.
Know you that in the elder days before the Aura Storms, when the ancient peaks of the Steel Mountains still thrust skyward sharp and majestic and the Hyskos tribesmen were but newcomers to the land, there existed by the Thunder River the pyramid and temple complex of Necropolis. The walls of this fortress were said to be proof against enemies and all things magical or natural. Know you also that here was said to dwell the great wizard Atenhotep at the height of his power and glory, and that he did lift his tower from the very foundation of rock upon which it rested.
Most grand and terrible of all Atenhotep's work was the great inner tower; for it was there that the wizard's most prized possession, an eldritch jewel known only as the "Soul Gem", was said to rest. Legend says that it was like a great white diamond and that it glowed with the brilliance of the sun. In years long past it had fallen from the sky and landed in the foothills of the
For the stone Atenhotep raised up the great central tower and filled it with many horrible creatures and deadly traps and, using a great incantation, he did wrest the tower from the very fabric of time and set it apart so that those within would not be affected by the passage of years. Thus it was that his traps never faltered nor did his guardians age or need food. Locals whispered that Atenhotep would, at times, set a prisoner free in the tower merely for the sport of his beasts. Some tales tell that his power was so great that he even taught the gem to protect itself from those who would take it from him.
But despite his great power there came a time that Atenhotep did leave on a journey northwest, over the Thunder River, and did not return. At this time there came a great multitude of superstitious peoples from surrounding lands who laid siege to and threw down the great tower. And it came to pass that despite this seeming victory over their former master the people did shun the area and it was said that on certain nights, when the stars were right, the great tower of Atenhotep could still be seen.
