I personally think its the crystal from vaders lightsabre, and i think kylo will get it at some point and perfect his sabre, we know his crystal is flawed, which make his all raw and un contained
Ordered 2 Lukes from Nippon, so stoked, might order a third from one of the other places to try them out
Ah yes vaders crystal, that totally makes sense. I like your thought on kylo using it
