I know you're GM and all, and different coloured lightsabers are not worth making a fuss about... But I've never heard of one light saber being able to hold multiple crystals. In regards to Sep's character.

I'm curious if you have some source to draw upon for this. Based on your post, the purple blade was meant to be thinner, isn't it actually much much easier to simply make some switches to change lightsaber blades to special settings? Like turn it into a more concentrated blade, or make it a thicker blade with the flick of a switch.

Also my character will probably head to the hangar. I'll post soon.
