The Taigyn River was a river within the South March Lands, it began up in the southern portion of the Branath Mountains, near Fort Taigyns. As it flowed south towards the Tabbard Reach, it was joined by its tributaries coming from the Shingle Mountains. It also flowed by Fort Darymahn. (map)

During the Rising, it was a proposed avenue of assault for the Earl Hanth's Charisian Expeditionary Force; whereby Fort Darymahn would be re-taken and he and his men would continue up the Taigyn River. (MTAT)
