The Argent Avenger has jokingly been called a lightsaber by many players in WoW, because of its "energy blade". It can also be enchanted Demonslaying or other "glowing" enchants to give the lightsaber different colors. The Icy enchant is a good way of turning this item into a "facemelter."
Is a tribute to the iconic Jedi swords, lightsabers. It can also be transmogged!
