Zül

Zül is a powerful dead, said to be as old as the Land itself. As the Principle of Slaughter, he is venerated by a cult of maddened mureders, The Reach of Zül, who believe their patron will eternally torment those they kill in hatred and forever protect those they kill with love in their hearts.

In the Year 713, Shinjo Baelon led a party of Gold Magistrates, shugenja and Rengoku Exorcists against the ancient dead and fought him again and again, tracking and harrowing him all the way to his lair in the Land of the Dead. The heroes came through, defeating The Roaming King, though few came back from the ordeal, and none of them intact.

Reappearance
Prior to the events leading to Game 4 - Yggdrasil, the Spirit Tree, members of the forgetten Reach of Zül cult managed to have the guardians of the Heart of Slaughter move it from its resting place to Nime-Yu. While in transit, the Reach of Zül attacked the Void Monkey guardians and their Rengoku Exorcists allies and taking possession of their master's prison.
