The main tributary of Alsuriea Nahr (Speed's River) bordering on the Rhachloa Downs and running into the low-lying southern Krokesteppe. As it diverges across the steppe, the waters take on a rich earthy red hue and diverge into many thin, shallow inflows that dissipate gradually into the earth. The bright red clay found here produces stoneware that has become emblematic of the region.
The river is checked at three locations by three ancient Armorcian caerburgs. The Military Republic of Altonbrun controls them now.
