Crossguard lightsaber

The crossguard lightsaber was an ancient lightsaber variant with three blades—a primary blade and two vents just below it called quillons—or a physical crossguard. It was once common among Makashi practitioners by the time of the Great Scourge of Malachor. The Sith Lord Darth Atrius wielded a pair of such lightsabers imbued with his anger. Later, during the High Republic Era, Jedi Master Stellan Gios wielded a crossguard lightsaber with an additional, folding physical crossguard which supported the quillon blades. First Order warlord and later Supreme Leader Kylo Ren wielded a lightsaber where the quillons served an additional function as vents to balance out an unstable, cracked kyber crystal.
