Sky Crystals

About It
The Sky Crystals are what keep the islands in the sky. Each of the sky islands has a central crystal which air spirits surround, giving their power to it which is then channeled to small shards around the islands, which act as focus points, to keep the place air born.

History
      When the Air    Crystarium Sprite observed the wars that were raging in the world, it came up with a plan, to raise up some land where people could live without war. It gathered many of the air spirits together and worked to make the plan a reality. 

      It created 4 crystals, each only slightly larger than a man's head and each was placed in a cavern and a s the spirits gave them power a large chunk of earth was raised into the air. However the Crystarium knew it wasn't enough for people to truly live on and more was going to be needed so created shards, no bigger than a person's index finger and shot them into more ground. The shards were connected to one of the crystals and would gravitate towards that crystal. This provided much more land for each of the 4 and they slowly became populated. To stop them moving around too much bridges were constructed.
