Fisherbabes Writings

I have hit a bit of a technical snag though, my story revolves around some semiprecious stones, which hold the key to the whole story.  I have just introduced two more stones that will bring it all together and when fitted all together the stones are used to contain a thousand souls.  The original warlock destroyed the stone and dispersed it to stop the stone from ever being used again, but another warlock is bringing them together so that they cannot be used against him, however I am a bit lost as to what to do with the stones.  Do they all come together and then they suck the souls out of him?  Why are they so important, they need the souls to keep the balance of good and evil, so they can’t dispose of the souls entirely either.
