I believe that the giant Flying thing (Whatever it may be) may actually be a titan, reason being. There are suppose to be 4 biome specific Titans and 1 king titan. So I looked at the picture a little bit more, and it occurred to me that there is nothing but sand in the entire image so that brought me to the conclusion that the image may actually be a desert. and that thing in the sky may be the biome specific titan. (maybe) There is only one down side to my thought, the small titans are in the domes or force fields and I didn't see anything that looked like one while I was looking around. I have more to say but for now I'm keeping it like this.
