The last remaining true dragon sanctuary in the world is a placed called "Hullenhoshi" It is hidden high in the Himalayan mountains. It is said to be the birthplace of dragonkind, how much of that is true remains vague since dragons aren't very gregarious creatures are have little (common) culture as a species. In any case, it was at least an important roosting ground. Presently, the sanctum is guarded by the Gold Dragon Li Jeng and a few others who call themselves "The Most Noble Order of the New Dawn"
