The river Kek is the main transportation route from the Spinal Ridge mines in the south of the Katlhan Strip, near Gángar, to the Khamadian outpost Nabak in the north, as well as their harbor on the coast. The river cuts through several biomes and traveling the river gives one a good idea of just how diverse the continent of Celenia really is.
It runs all the way from the mountain range, through the dark bogs and up through the Dim Grove to Nabak, just before it reaches the Morvátian Expanse.
The river Kek is a combination of two smaller rivers joining just north of the bogs, comedically named East Kek and West Kek respectively. East Kek is the larger and wider of the two, which is frequently used for transportation over the western one. While west Kek can be used, it's occasionally quite thin, especially during dryer seasons, which can cause issues for deeper draft flatboats.
