Sinai Mio

Set in 2540. A big time skip from now, people had to evacuate earth because of nuclear warfare some time in the 2060’s, people scrambled the galaxy to find a new home. A way of that including wormholes in space to their advantage. About 100 members stumbled upon a planet in a solar system not too different from ours, similar gravity, and lifeforms with similar DNA. The thing was that the Earth-like planet was consisting of floating islands, thick, leading down all the way to the core (think of it like the outer end islands from Minecraft but mountainous terrain and looking basically like Earth) that gravitational waves from the core held together so they don’t float away. They colonised islands, and built a civilisation, Seraph, of over 50000 people living on flat terrain at the top of one, big mountain on a large island, with others living on different ones like fathers. Not long ago, the HQ managed to establish a connection with the rest of the humans scattered around the universe, and have been communicating since and in some time will probably be expected to visit (them staying would vary). You and Sinai were born somewhere in Seraph. Met in pre-school and stuck since. You had a pretty normal childhood, and once you turned 14 you joined an organisation that went on expeditions to explore more of this world. And since then you stuck with a team. Mostly these missions consisted of about 10-18 people going out to an unexplored area, scattering into pairs of 2-3 for around 2 days and adding it to a virtual map that later gets pieced together back at Seraph. Sinai is now 16, and right now, you’re travelling through unexplored terrain on a type of vehicle like hover-bike about 14 miles out from the scatter point, stumbling across a colossal hole, looking like some sort of crater of the mountain that reached up above the clouds. It seemed consist a new type of crystals that neither of you could identify. Got this image off Syao_1412 on Pinterest
