Lunafreya's hairpin



The hairpin gifted to Lunafreya Nox Fleuret appears in Kingsglaive: Final Fantasy XV and Final Fantasy XV. It is a golden hair ornament with a large round clear jewel in the middle surrounded by two "lids" of smaller round jewels that could invoke the image of an eye, or a full moon amid stars. The filigree pattern of the pin is similar to King Regis's.

Story
The hairpin is supposedly a wedding gift from King Regis of Lucis to Lunafreya who is to marry his son, Noctis Lucis Caelum. The hairpin was to be delivered to her by Crowe Altius of the Kingsglaive to see Lunafreya safely to Altissia for the wedding. Things went awry however: Emperor Aldercapt brought Lunafreya to Insomnia for the treaty-signing ceremony, and Crowe was killed during her mission due a conspiracy of the Kingsglaive plotting to betray the Crown.

Crowe's earthly possessions are passed onto her friends Libertus Ostium and Nyx Ulric. Nyx meets Lunafreya during the party at Caelum Via to celebrate the peace treaty and gives her the hairpin and relays the news of the gift-giver's dire fate. Lunafreya is saddened that the Glaive entrusted to give her the gift passed, but deems the gift lovely. This exchange may have been planned, as Titus Drautos (who was the one to give the hairpin to him) had changed duty from guarding the gates to guarding the princess, and was also at the party as his alternate identity General Glauca to witness Nyx pass it on.

Unknown to Lunafreya and Nyx, the hairpin is a tracer. Crowe had a watch to track it, but now it allows Niflheim to keep track of Lunafreya. Nyx realizes the hairpin is tracking their whereabouts due to Crowe's watch when war breaks out in Insomnia and he tries to escort Lunafreya out of the city when she holds the Ring of the Lucii. She picks up the tracer and Nyx drops and tosses it into a machine that explodes.

Lunafreya wears the hairpin in the otherworldly wedding on the throne of Lucis.
