Yujantze is the right hand of Shianze, Lord of Gaztoko. For a thousand years the Lords of Gaztoko have guarded a secret buried deep in the bowels of the castle, so well that its memory has faded in the outside world.

With his health failing the ageing Lord Shianze summons Yujantze and his daughter, the beautiful Princess Lin Te Zun and reveals the closely guarded secret.

The Emperor discovers documents hinting at the existence of a powerful secret and seeks it at all costs. The search spells doom for Gaztoko unless Lin and Yujantze can find a way out.
