My loyal and trusted friend,
I write you because I can't reach you in person, but I trust no one to deliver this message. I have seen a future that brings me great foreboding. We have functioned a long time without a truly crowned Source. Your leadership has brought a chaotic Underworld order again, but even we must admit my friend that our losses have been great over the years. I have done much research and spent long days in meditation. I believe I have found the power to recreate the spell we lost with the Grimour, the spell that will give you unquestionable authority, but it will not matter if the future I have seen comes to be.
Over the years, the Charmed Ones took on many different roles in the fight to defend good magic. As they got stronger, the world of magic opened up to them and they became more than good witches that battled demons and warlocks - they became defenders of good magic itself. That meant that they served as more than just warriors. They instructed young witches when their whitelighters couldn't get through to them, they saved countless souls from giving in to evil, they helped bring about compromises when different sects of magic disagreed on an issue, and as they watched their children turn to adults before their eyes, they performed their most important task of all - they protected and prepared the next generation to take over where they would eventually leave off.
It is that next generation that concerns us the most. For while the Charmed Ones were strong, fate has brought about a much stronger power to take their place. Someone must have had a hand it in, guiding and directing them because they would have never come together in this way on their own. But the deed is done, and if the children have discovered the power they can tap in to, the solution will not be found in this time.
You must send someone to test them. It will not be difficult to find them alone these days. The test must be difficult or we will not know the strength of their power. Remember that three of them have inherited unaltered powers from their mothers and can invoke their spells without need of the others. It is the others that will combine against an unknown evil. If they succeed, our only hope will be found in the past.
This test must be performed before All Hallow's Eve as that is the night we will strike if it must come to that. You will not need to send word to me of the results. If they have not yet found the power, our solution will be an easy one. If they have, I will know and I will send you instructions for where we must travel and what we must do. I will prepare now for the worst.
Yours always in all things,
Melia
