From publisher blurb:
Races of Center Space 5: Dijat is the ninth volume in a series playable races for the 5th Edition rules. Each race in the series is from the Center Space setting. While the Center Space is a science fiction setting, the races can easily be used with other genres.
This volume presents the Dijat—a race adapted to life in the desert, they are tough and virtually inexhaustible.
This book contains a racial description and a new racial feat for the Uhr, as well as suggestions for adapting it to other settings.
