A StoneKeeper can be bound to a specific MetaStone by using a blast of Meta_G.
When this happens the Metastone being bound to will appear in the Stonekeepers forehead.
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 Stone Keeper 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.
