High atop the mountains of the Dragon lands, in remote dojo and obscure strongholds, dwell the Master Sensei of the Mirumoto family - a tiny elite group of men and women who have attained true mastery of not only swordsmanship but also of their bodies and souls. Their primary home is Morning Frost Castle, but they also have several lesser dojo scattered through the most remote and inhospitable corners of the Dragon lands. The Master Sensei are very few in number, seldom exceeding two dozen in total, and those who would join their company must meet with their personal approval. Some Mirumoto samurai have spent decades struggling to prove their worthiness to the Master Sensei, while others have been admitted on their first application. Although the nature of the Master Sensei is more amenable to those who have followed the ways of the Taoist Swordsmen, they do not play favorites and more than one Swordmaster or Niten practitioner has joined their ranks.
The Master Sensei are isolated even by Dragon standards, and rare indeed is it for one of them to leave their remote dojo and visit the rest of the Dragon Lands, let alone the Empire as a whole. However, on the few occasions they do emerge to influence the world outside, their impact is always profound.
