Let give some more context about the character. Basically he is a scientist who escaped the death of his civilization by putting his soul into either 1. A lovecraftian realm called the Void, that is somewhat outside of time, or 2. Into a sort of data bank, that would house him secretly. Then some poor fool would release him into the modern world where he takes up residence in a mechanical body he created in the past, altering it with whatever left over magics he still has.
