Ok, I guess I can go ahead and do my JOB as DM, and give you what I have:
*Ahem*
All of the PCs are affiliated with House Phaedran, be it by blood, by oath and duty, or whatever the case may be. Bottom line: You are all, for whatever reason, loyal to House Phaedran and you've become dependent upon the powerful reputation of the House. But the group of you are not just members of the House, you are Scions of the Power of House Phaedran. You, each one of you separately, and all of you together as a group, are being groomed to lead the House into the future. But rather than keep you under heavy guard and cloistered away from danger, the Elders of House Phaedran have seen the wisdom of equipping you to face any challenges that may arise so that you may defeat those challenges soundly. And, to that end, you are expected to continually hone your skills and increase your abilities.
When the Wizards and the Seers of House Phaedran became aware of the danger of the DweomerFall, they naturally thought of you. The DweomerFall is a condition whereby the very essence of magic is being slowly drained from both the Feywild and the nearby Prime Material Plane. The rate of drain is quite slow, but the Eladrin tend to take a long-range view of such things, and over a long enough time, the DweomerFall could conceivably threaten much of the way of life that you now know. The Elders have been clear: The time to stop this DweomerFall is NOW. The rest is in your hands. The Elders do not expect you to solve the mystery and the problem in a weekend. They know that the flow of information may be maddeningly slow at times, but they do expect you to make occasional progress and follow any leads that fall into your laps.
