Branches of the Drake River run all throughout Thunder Rift. It is a gentle river flowing north to south, one branch ending in a swampy delta northeast of Lake Ganif.
The Drake River is one of the primary means of trade and travel in Thunder Rift. It connects all of the major towns in Thunder Rift, from the city of Melinir and the small village of Torlynn to the northern town of Kleine. Merchants travel upriver by poling themselves against the gentle flow on large wooden barges. The village of Torlynn is known to supply these barges and often travels with them and their lumber by means of the river.
