When the teaser trailer for 'Star Wars: The Force Awakens' came out in late-November last year, fans from all over the globe showed tremendous appreciation for every little bit of information that was shown - except for that one single moment - when the cloaked character (who fans are speculating to be played by Domnhall Gleeson) activated his lightsaber.

Whether it was because the fans wanted to hold on to everything about 'Star Wars: Legends' (the collection of stories and novels that was once known as the 'Expanded Universe'), or because they just had their own ideas of what things should look like in the Star Wars universe, one thing was certain - the whole fanbase was split into two regarding how the new lightsaber looked.

A lot of criticism was aimed at the supposed "design flaw" of the lightsaber that was shown in 'The Force Awakens' trailer - the cross guard beams were useless, dangerous and aesthetically unpleasant. Of course, there were as many lovers of the new lightsaber as compared to the haters, and they constantly defend the ingenuity and creativity of whoever designed it. The only question on all of the fans minds now is: How did that cross guard lightsaber ever came to be?

Fortunately, the answer may be closer than everyone thinks. According to a report by the International Business Times, the novel 'Star Wars: Heir To The Jedi' already gave a hint on the new lightsaber design. According to Hitfix, the Star Wars novel, whose events take place between 'A New Hope' and 'The Empire Strikes Back,' tells the story of how Luke Skywalker finds an "odd" lightsaber that had crystals in it. They also speculated that this particular lightsaber's design may play a part in the creation of the one that was seen in 'The Force Awakens' trailer.

According to Jason Ward, a writer at Making Star Wars, he was told by a source that the lower part of Kylo Ren's lightsaber (the one shown in 'The Force Awakens' trailer)  holds a crystal chamber with protection. It was also stated that the weapon is yet incomplete and that Kylo Ren still had to find some of the parts.
