The Hsien (or Immortals) are the personal elite guard of the Emperor. They are the most self-sacrificing of the chosen, the best of the select, devoted to the Emperor until death without thought for themselves or for anyone else.

They are specialized in intense combat actions and in going into or repelling assaults by fire power, close combat or counter attack. The Hsien are the Imperial Agents, sent to whatever place as the materialization of HIS will. Feared and respected, they have complete power to take decisions, execute them with severity and then disappear from the scene.
