There's a new event coming to FFXI servers called Celestial Nights. The FFXI PlayOnline website has some information about it; more will be coming on the day of the event.
A new special event called "Celestial Nights" will commence at 1:00 (PDT), on June 29. During the festival of Celestial Nights, people write poems to their faraway loved ones on strips of brightly colored paper, which are then tied to bamboo stalks. These arcing stalks of bamboo represent a bridge that spans the great river in the night sky. What will this event hold in store for Vana'diel's adventurers? Gather your closest companions and find out together!
Further details regarding Celestial Nights will be released on the day of the event.
