Causing external explosions just by picking up a sword? That sounds really cool! Unless the explosions are from the sword calling an artillery strike on your head. That'd be much less cool. Chewbacca seems rather unconcerned that the rubble nearly hit him though. I guess it is rather difficult to look afraid or concerned with all that fur.

I do wonder why Kanata brought them all back inside though. Bringing the laser sword out with him when the Peace Moon fired off and drew the giant crowd would have made much more sense if he wanted to give it to someone out of this group of visitors that won't immediately run off. Maybe there's more stuff that the group needs to take with them? If the place is going to be destroyed, there's probably other things Kanata has that he wants saved. There's gotta be more artifacts he has than just the lightsaber, assuming he was actually a traveler in the movies as well.
