The Droa River is the main tributary of the Raiteso River. It has its spring in the west of the Ustalavic county of Caliphas. The river runs nearly due east; it is bordered on its northern shore, for its entire length of about 35 miles, by the Albria Woods. At the river's half way point it flows past the settlement of Anactoria. The Droa flows into the Raiteso River, where both rivers leave the Albria Woods.
Along its banks may be found many craftsmen in small communities plying their expertise and trading predominantly with the rich of the city of Caliphas. The craftsmen include vinters, perfumers and quarriers of the alabaster found in the region.
