I was spent last night at the end of the session, so I didn't get to the speech I wanted to.
As the Lord of Slaughter fell, the Couatl came out of her trance, and the two shimmering vortices collapsed. She opened her eyes and spoke to each of your minds.
"Congratulations, heroes. You have achieved victory, and won back your world. Your names and actions will be remembered in prayer and song for ages. For this was your fight, for your world. The High Table and their agents may have guided your steps, but the decisions and actions were yours alone. And that is how things will be, from now until the Reaper's Final Harvest, should you wish it.
When the Cube is complete, the days of the Gods and Demon Lords walking the Urth will pass, although their faithful may seek their power and guidance still. But this is now your time, earned by your own labor and your own sacrifice. Make of it what you will.
Of sacrifice, you already know much. May you accept mine."
And with that, she collapsed into the Positive Tile. The shimmering walls holding back the forces of the Dark One collapsed as well, and as legions of Shepherds, Undead, and Demons raced towards you, the Nameless Elf completed the Cube. With but a thought, the walls between the planes were strengthened, and the Dark One was cut off from the Plane Prime. Shepherds and Undead collapsed into a jumble of decaying corpses, while Demons blinked right out of existence.
And when the Nameless Elf looked down at the Cube, it too was gone.
Welcome to the next evolution, and thank each of you for playing in my campaign.
