Welcome to The World of Kensei, a world setting and rules for Dungeons and Dragons 5E players.
The World of Kensei is a place of great heroes and stark evil, encompassing lands of ancient myths and high peril. Brave warriors dare the ancient shrines of the old gods, now home to evil creatures. These are the lands of Tatsu, a new continent of beauty and ages-old evil. Tatsu is yours to adventure in, defend, shape, and rule.
