Yeddan is the last of the seven planes of Hell and is the dominion of Hesburr. Yeddan is a desert world, covered by coarse red sand.

Yeddan is a land of twisting canyons and windswept deserts. A constant wind blows towards Hellas and the Pit creating fierce sand storms in exposed areas. Yeddan has both a day and night cycle. During the day the temperatures rise to a stifling level while at night they fall below freezing.
