Cryseed

A cryseed is a crystal seed that when planted will grow thousands of crystal roots, called cryroots. Deep within the ground, these cryroots will grow in all directions. After they finish growing, they will turn solid and transparent and will begin to lift the land around the cryroots up into the sky creating a floating land mass called a skyland. The cryroots will lift the land until they have reached their unique altitude and will inherit a coloured glow depending on the amount of air pressure that there is at that height. This newly made skyland could drift in any direction from wind but would not be blown up or down from its altitude, the cryroots attraction to it's unique altitude would be too strong; this attraction is called crytraction, eldOnia's natural opposition to gravity. If a skyland were to crack in half, the two pieces should still float at their unique altitude. If by chance, any of the pieces, when separated, had less cryroot than land, that piece would start falling, depending on how much that piece depended on the other as a whole. Another way this could happen is if too much cryroot is mined away from the skyland.

If a cryseed's mushroom-top like crystals are cut off or broken they will grow back. The pieces will then forever be attracted to that cryseed unless a shift of crytraction occurs. This shift of crytraction can be achieved by secluding the pieces away from the cryseed for a period amount of time. The pieces will then only attract to each other.

Uses
Before the pieces had their crytraction to the cryseed shifted you could have used them locate the skyland the cryseed was planted in after they have left, by simply tying a piece to a string and holding the other end while watching what direction the piece was pulling towards.

Shifting the crytraction of the pieces to each other can be used to create two rings for marriage so that each partner who wears their ring could feel the direction of their spouse. If marriage isn't your thing yet make a ring for all your friends so they can find each other easier or use the crytraction between pieces when building mechanical devices.
