This year at the Tokyo Game Show, Square Enix held a Final Fantasy XIV: A Realm Reborn event where players had to beat a special version of the Titan primal. If they succeeded, they would pull the name of a server out of a hat and everyone on that server would get a pair of cactuar earrings. People quickly defeating Titan enough times so that every server got the cactuar earrings. So then they had another event where they had to defeat Titan. This time if they succeeded, they would pull a server name out of a hat and every player on that server would get bomb earrings. It should come as no surprise that again Titan was defeated enough times so that all servers received the earrings.
As I was running around doing the Halloween event stuff, I grabbed my earrings from the Itinerant Moogle. Here are pics:
