The Reisendrelle is a river in the south of the main continent, flowing from southern Andor through Murandy, where it joins the Storn at Lugard (TWoRJTWoT, Map). North of Lugard, it was twenty paces wide, and up to horses knees, flanked by baked mud and stones on either side, suggesting in normal times it was wider (ACoS, Ch. 12). Tributaries include the Armahn.
