Cyon would most likely be a jedi so he may would most likely have a Aneton kyber crystal, when put in a lightsaber the lightsaber gains the ability to steal other kyber crystals energy, basically becoming a lightsaber killer, the Cyons lightsaber would also be dark blue due to him being on the light side but having the ability to take out both the jedi and the syth if he really wanted to

although unlike other lightsabers Cyons lightsaber would most likely be shorter then normal, basically turning it into a knife, although this downside is countered by the wrist strap attacked to the lightsaber, made out of a thick metal that the aneton lightsaber blade can't cut through, it was also flexible so he can take this on and off at anytime, this also gives Cyons he ability to rotate his lightsaber at fast speeds
