The Zin Order originally known as the Zin Family Jedi Sub-Order also known as Zin Family Sub-Order or Zin Sub-Order was a branch of Gray Jedi in the New Jedi Order. The branch was created by Kale Zin when members of the Order asked him to join and Kale said that he would join the Jedi Order under the condition that they allow him to create a Gray Jedi sub-order inside the Order.
However the Zin Sub-Order, unlike most Gray Jedi, believed that the Force was in fact good not indifferent. The ultimate belief was that the Force was a good living being and that there was an other "force" at work in the universe that wished to manipulate, copy, and outdo the powers that the Force created.
Later the Order disolved because members of the sub-order decided to go back to the ways of the Jedi.
Centuries later Jedi Knight Qyv Xinn discoverred Pock Zin's journal and found out that there was more to Zin's beliefs than what his son had used. Pock's ultimate belief was that the Living Force was a living being that created and transformed the universe over time. He also believed that the Force was in fact a good being not indifferent or conflicted. He reffurred to the Force as Ellunvir.
Pock believed that what the Jedi viewed as the Dark Side of the Force was in fact an other being that was created by the Force that wanted to overpower the Force or become equal to it. He called it the Dark Power
Pock later found that there was not just two beings but a completely innumerable amount. Most of them followed Ellunvir and some of them followed the Dark Power. Pock believed that these creatures and Ellunvir were what gave sensitives their powers. He chiefly believed that Ellunvir gave powers as a gift and that no matter who you were you could use your powers for Ellunvir or for the Dark Power. A person had to make a choice to choose witch side they wanted to follow.
Pock later put all of these things into a holocron witch was found two years after Qyv found Pock and Kale's journals.
All of Pock's beliefs were the beliefs of the Zin Order.
