The Face of the East Castle (CB1) was the northern castle which would host the Yasuki's diplomatic endeavors, as its distance from the Shadowlands helped ensure the safety of it's guests. It was also the major centre for lumber harvesting, and permission to harvest from Shinomen Mori was given by the Naga before they entered their slumber. Nezumi also used to deal with the Crab here, but stopped after the dealings with the Naga.
