The stones (formerly called Gems) form a circuit when combined with each other forming a positive feedback loop unlocking their full potential and releasing the INFINITE power stored inside. The gems true potential lie within the users mastery of them individually.
The stones have always been mysterious and a subject of debate and discussion for years so it’s fun to see them fleshed out a bit more. I prefer the still have a twinge of mystery, but that’s just me.
Here are the new owners and new descriptions of the stones:
