Cleanse Sef Iwen's remains.
As I've said, I'm unable to interact with the material world. I am able to dominate a creature to control its body, but I find it deplorable. In essence, it is enslaving the poor creature. What I want is a body of my own. If you build and animate a golem, it would be devoid of intelligence. A shell. One that I could inhabit without issue. Doing so will require that my soul is not anchored to anything else in this world, so I need you to remove the spell binding my spirit to my physical remains.
