[@tal0n] [@Gat Izen] [@KitsuneDarling] I like being selected. It's better that way , I think. 

I was thinking about this man that told us where to go and I asked myself this : " Why would a man gave some people he never met something that precious ( the stones ) ?  " The answer ? Because he stands to gain something. The corporation that you said Gat could be the ones that found the stones and this man stole them and gave it to us in order to take out this corporation ( of course our characters will not know the real reason until it's too late ). The stones merge with our characters and that's the reason the corporation wants to kill us. 
The man's connection to any of us ? Either that he knew our parents ( in which way we decide ) or the stones "chose" us. They were only compatible with a small number of persons. 

The corporation ( this is in the future ) will have found more of this stones and made other people ( that work for the corporation ) powered like us ( other powers ) that will hunt us down.

How those ideas sound ?
