Taku "Crix" Matsuki Taldrya was killed in action during the Eighth Great Jedi War and his lightsaber has now become a relic held by Clan Taldryan
After Taku "Crix" Matsuki Taldrya's death in the Eighth Great Jedi War, all of the former Archanis Quaestor's possessions were transferred to his successor, Andan Taldrya Marshall. He carried the lightsaber for a while until he constructed a second saber using the same hilt design with an orange blade. After consulting with Consul Duga Taldrya Arkarso the original, white-bladed saber was declared a clan relic which was to be passed down to all Quaestors who lead House Archanis from that point forward.
The lightsaber gives the wielder no special powers, it is simply a piece of Clan Taldryan and House Archanis history which has been preserved and is passed down from one leader of the house to the next.
Because House Archanis is currently closed, the lightsaber has remained in Andan Taldrya Marshall's possession and will remain so until the house is reopened and a new Quaestor appointed.
Note: Since the lightsaber is a custom saber, only Quaestors who can request custom lightsabers are able to display the lightsaber on their profile. If they aren't ranked high enough, they are still given the lightsaber and it can be added to the profile once the Quaestor reaches the correct rank.
