He has a really sweet personality and he looks just like Sidian.
He lives in a poor village somwhere in the Crystal kingdom.
The Crystal kingdom is getting ruled by queen Opal and king Topaz. Let's just say that the king and queen don't rally do a good job at rulling and all they care about is money and fame.
Sidian is totally ok with that since he doesn't know what it's like living outside their Castle.
