From the last entry in the journal of the second simulacrum of the “Faceless One” destroyed by the party, found in the palace of the Beast King.
The worms stir and writhe even now. The land is like a rotting apple infested with them. Soon they must burst through its thin skin and swarm across the land. The great power is stirring. This decayed monstrosity of the world will be made clean once again. The Master told me this, so it must be true. With the return of the king, the next age of Man will come and the Conqueror Worm will rule all.
GM will post other notes soon.
