Starting in patch 2.45, players can pledge their everlasting devotion to a significant other in a Ceremony of Eternal Bonding.
You can choose between three plans on the FINAL FANTASY XIV: Mog Station: standard, gold, or platinum.
The standard plan will provide couples with eternity rings, ceremonial attire, special hairstyles, and commemorative furnishings─everything needed to celebrate a blissful union before the eyes of gods and men.
Players who select the gold or platinum plans are in for an optional dash of extravagance . Both offer color schemes for the chapel decorum, choice of cutscenes played during the ceremony, and dyeable attire.
* Players must apply via the FINAL FANTASY XIV: Mog Station to hold a Ceremony of Eternal Bonding, and then make reservations in-game after progressing through the special quest.
* Reservations for the following week start every Friday at 1:00 a.m. (PST). Players must wait until Friday, December 12, 2014 at 1:00 a.m. (PST) before making reservations.
