Emberfall. The Pyre of Creation, #2

The universe is dying - and the order sworn to save it has been selling that salvation to something that wants to freeze creation at its first breath. Orin, a disgraced former Seer, knows what the Pyre-Seer Order's great ritual actually costs. What he doesn't know is that the real architects aren't human, aren't alive in any meaningful sense, and have been patient for longer than civilizations have existed.
One shard of the original fire. One ancient being making its final choice. One dying universe that deserves better than what's being planned for it. The cold is coming. The only question left is what burns before it arrives.
