Lake Daenfal is an east-west running lake in West Halla, Melhalla, which also forms the border with the principality of Rathain. The cities of Daenfal and Backwater can be found on the northern shore. At one time, the Severnir River flowed into this lake, until the river was dammed and rerouted after the uprising.
The River Arwent flows out of the lake and into Halwythwood. The topology around this area consists of stepped bluffs and shear escarpments, sixty spans above the river. The west bank where the River Arwent connects to Lake Daenfal is known as "the Rim".
