Well that, and because the ROB that yanked me decided that he wanted to be entertained... Wonder if I can give Palpy a heart attack?

One night you fall asleep in a hospital bed on Coruscant. Then you awake a dimension away. No Force or magic. Not even a bit of cybernetic enhancements to give you an edge. Just the body of a bastard prince, who lives on borrowed time. It's too bad for the locals that they got a Sith stripped from his arcane powers and thrown in the snake pit that is Westeros.
