A new world event is about to take place in the lands of Eorzea called Bombards Ablaze. Bombs have appeared near towns around the world and it is your job as an adventurer to eliminate these creatures and gather their ash. Using emotes you must lead them to nearby Festive Furnaces and incinerate them.

Players can participate in the event from August 11th until September 5th and will be able to gain a variety of swimsuits. As well as this you can create and download wallpapers of your character in a swimsuit.

For more information on the event you can read the post on the Lodestone via the source below.

Edit: Here is an example wallpaper taken of my own character after the event began.
