Lands of the Ton'keena is a Japanese-inspired fantasy setting based on the Pathfinder tabletop game and ruleset. It is developed by three Pathfinder and other pen-and-paper roleplay gamers.
After the ancient Elves and Unseelie vanished from the surface of the world, a race of catgirls known as the Ton'keena began to thrive. They rediscovered magic, sailed to every continent, and settled across the known world. Today, even the older races cannot deny the supremacy of the catfolk.
This game is primarily set on a Japanese-inspired continent home to the Heibesian Empire, one of the greatest political entities the Ton'keena world has ever known. Most of the setting revolves around Imperial culture.
This game uses the Pathfinder ruleset, however there have been several changes which one can find in the Misc > Gameplay Changes section. The biggest is the magic system, which is completely unique to this setting. More under Magic and Casting.
It is a non-commercial project. One can find the official Pathfinder website as well as the game rules here at http://www.d20pfsrd.com/
