Regardless of how far away your galaxy is, I think you'll find that people are pretty much the same all over. So, you just know that once word about Kylo Ren's cool three-pronged lightsaber starts to spread around the Galactic Empire, fancy impractical lightsabers are gonna become kind of a thing. Next thing you know, there's gonna be artisanal lightsaber shops opening up in Coruscant's hipster district and creatures who don't even have arms will spend days waiting in line to get the newest model from the lightsaber store.
