A StoneKeeper can be bound to a specific MetaStone.

When this happens the Metastone being bound to will 
appear on the Stonekeeper. 

This metamorphism will also have other effects on the StoneKeeper that will be revealed 
when the binding completes. 

Binding can only happen once with each StoneKeeper 
and once completed is irreversible.


When bound to a Metastone the StoneKeeper will attain 
the Ancient Intelligence (Ai) 
of that stone.


Note: Binding a StoneKeeper with a stone that matches its day increases the chance 
of rarer changes appearing in the Metamorph process.
