The image reads >イバラードへワープ!>上昇気流にのった浮島達
Which translates as..>Warp to Iblard!>The floating islands which ride the updraft
Iblard is a setting which has received very little attention in either English or even Japanese materials. It is the chosen setting of Inoue Naohisa, who drew it for manga primarily until 2007 when he directed the Studio Ghibli adaptation of the setting, called...>イブラード時間>Iblard Time
I give the Japanese because from my limited search it isn't well known in Japanese even, much less English. I'd never heard of it, for sure. So if you want to look it up the Japanese might help.
