Ichani are outcast magicians in Sachaka who have been banished to the wastelands. Emperor Vochira banished them for causing economic damage by thievery, killing other peoples slaves, and attacking and robbing magicians.
They have a strong distrust of each other, and battle among themselves, which makes it hard for one person to become a leader. Kariko is one who has some success.
