From publisher blurb: A river kingdom of haunted ruins, ruled by crocodiles. FIVE DAYS BY BOAT, UPRIVER You come to wide lake, watched by limestone cliffs. Shapes lurk in the water. Shapes wait up ahead. Riches clog Mr-Kr-Gr’s rivers — but its citizens build neither soaring temple nor palace spire. It is forbidden to set stone upon stone, in Mr-Kr-Gr. The crocodiles say so. The crocodiles rule, here. What stone cities exist in Mr-Kr-Gr are overgrown ruins — haunted by corpse-honey hosts; mosquito witches; gods trapped in the prison of their idols. These old cities are proscribed, also. The crocodiles say so. Doesn’t stop downlander expeditions, though. Old cities are always full of treasure. Mr-Kr-Gr is an adventure setting inspired by riverine life, the crocodiles of Negeri Sembilan, and the lost cities of Southeast Asia. A rules-less, 44-page gazetteer filled with characters, locations, and detailed black-and-white art. Random NPC, encounter, and magic-crocodile generators.
