So on the topic of Erza's light saber is the blaster powered by the crystal or does it have it's own source? Knightmare · [Talk] 23:29, January 10, 2015 (UTC)
There is no clear-cut canonical answer at the moment, as far as I'm aware. However, delving into the Legends -- and specifically The Essential Guide to Weapons and Technology -- we get a schematic of the internal mechanisms of a blaster.
Explosive gas enters a chamber where it is excited by a power cell, then gets focused by a crystal and stabilized in the barrel, where it is then emitted. Some of these components are similar to a lightsaber, where energy comes from a power cell, is focused by a crystal, emitted, etc. According to this it is plausible that you could combine the technology together into one device as we see Ezra has done, though I think this is the first example we've seen of a combo blaster-saber.
From what I've read in Young Jedi Knights: Lightsabers (and recorded in the lightsaber crystal page) lightsabers are very robust mechanisms that can work with very common components -- it doesn't have to be the fabled Kaiburr or Adegan crystals, or special power cells. Almost any tech will do, and the various young Jedi use all sorts of stuff. However I've never heard of anyone putting one of these special Kaiburr crystals into a blaster other than Ezra, and don't know if that is better or worse for its effectiveness. Perhaps someone familiar with blaster-smithing in Star Wars Galaxies can provide more info.
