Great Ritual (CTD)
The Great Ritual is the goal toward which House Leanhaun works.
Overview

The Great Ritual is what all Leanhaun who truly serve the house strive toward. Most of their actions are designed to bring about the proper environment for casting this potent rite. When the time is right, and they have gathered the needed sacrifices, House Leanhaun will save Arcadia and the Dreaming and redeem their house from Finellia's curse.
The purpose of the Great Ritual is to bring down Endless Winter on the Earth through the sacrifice of dozens of Seelie childlings and the majority of Dreamers in the world. This terrible sacrifice will be made to the Dreaming, destroying Earth's immediate future by eradicating most of its Glamour. House Leanhaun plans to preserve some few Dreamers by taking them into the Dreaming for a time. The backlash as the bright Glamour of the sacrifices sweeps like a tsunami through the Dreaming and inundates Arcadia should overturn the faerie homeland's stagnancy and tear away its rulers, leaving the realm cleansed and open for Seelie rulers to create a new, glorious Summer there. The Earth will fall to the Unseelie and into an age of untold darkness, bereft of most of its dreams. For that, the Leanhaun are willing to take the blame.
The house hopes that this will fulfill the conditions set by the wording of Finellia's curse. If it does, the house will at last be free. Gradually, the two worlds should begin to recover equilibrium as the Unseelie relax their grip, allowing the Seelie to once again rule half the year. As they take up their proper rule again, the Earth will turn again toward the light. Any Dreamers left, those the Leanhaun hid within the Dreaming (See the article Eternal Order of Dreams) and those born since (and more will be born; Glamour can never be utterly destroyed), shall be allowed to escape Leanhaun control and Dream anew. For a time, the Leanhaun may be reviled for triggering Endless Winter, but when at last all lies in balance, their house will take its place as the noblest and most deserving of them all.
