It seems that you don't know the history behind the Opticording Sphere quest, it was solved with each update CipSoft has implemented over the years, people found some mysteries and could only solve them years later. Currently my question can't be answered because probably there isn't a use for this item yet, but it may be related, because the final reward for Opticording Sphere quest brings more answers than conclusion. PS: I know this item is obtained from the Order of the Stag quest, but he matches some of the riddles from the Opticording Sphere quest.
