Seems a little excessive to gain a prophacy he didn't pay much heed of.
You got it back though yes? The hand?. Or at least a replacement. I seem to remember you having both?
Jedi are set the task of building their own lightsaber, its the last thing one must do before being named a Knight. I was in a group that included Jacen and Jaina Solo and I suppose I felt...well, like I needed to compete with them. I made my lightsaber haphazardly and in the training room when we were showing Master Skywalker our combat skills my blade shorted out before Jacen could pull his away.
I have been offered prostethics but it serves as a reminder to me of my pride to leave it as is.
