Yumeji was the rokugani word for the control exerted by Yume-do. Only natives and those who took on Yume-do's influence deliberately were affected by Yumeji. The more yumeji an individual had, the harder it was to pierce the Veil of Sleep to leave Yume-do, but while he remained in Dreams, he had far more control of his surroundings. Nezumi Name Magic could grant Yumeji, as could Naga Pearl Magic.
