River Karr
The river Karr is a large river north of the city of Karinthia, and that city took its name from this river. It is one of the biggest rivers on the continent of Polaris.
As well as being wider than many rivers, the Karr has a stronger current, which can drag weaker swimmers along if you do not take care.
As with all rivers, the Karr can be a good place to fish and most warm water river fish can be caught there.
