Orim of the Shadow:
We must have 2 things in order to lock the devil Zeruel back into the box: . The Sword of Binding, and the Soul-trap Crystal.
The Sword of Binding belongs to Sir Klaus Vasper, and the Soul-trap Crystal is owned by Magister Iker of Giran. Both of them are very prejudiced against Witchcraft and will need to be convinced to cooperate.
