The Sky Nation's world consists of many different floating islands and relics from a previous age. These contain different materials and have various uses to players when exploring. They are slowly being expanded with content updates.
In rare cases there may be special components from ships that have been abandoned there.
These islands make great platforms for building docks and bases.
Glaciers form in cold temperatures at varying altitudes. They are frozen water vapor that have amassed to large obstacles, made completely made of ice. Players will slide about on them, making them dangerous to mine from. Currently they do not provide any required crafting materials to players.
Bubble islands were formed from large bubbles of magma raising from the earth and their surface cooling in the colder air at high altitude. They mostly consist of stone and dirt, but still have big amounts of Molten Rock in their boiling hot insides.
