The Greater Oblako
Named by one the original colonists to Icarus, who happened to be Russian. When he looked up in the sky, he could see these great, pale beasts just floating around in the sky.... like clouds. Oblako is Russian for cloud.... at least in it's English spelling. (I looked it up online.... and everything on the web is true.) It was through these great beasts that they were able to settle most of the mushroom, rocky islands. The gave the people of Icarus much greater range than the swiftly deteriorating gliders that they originally used.
