First

There's no point in beating around the bush. The First was the first to wake up after Nightmare Fuel. As a consequence, he saw a little bit more than everyone else.

It was that "little bit" that dictated the rest of the Sleepers' lives. He created the first mirage. He was the first to learn the art of Sleepers - to mistake dreams for reality and reality for dreams. He taught other Sleepers to erase this distinction with their hands. He created the Steps - the way each Sleeper learns their craft. His level of craft is beyond the reach of any other.

His dreams sound and smell, they envelope you, and show you whatever you want. And then you will hear an ingratiating whisper that is equal in volume to a million voices and you will not be able to refuse him. He doesn't have to be near you.

Every Sleeper hears the First and the First hears every Sleeper who has passed at least one Step. The First wants to erase the line of worlds completely, which would inevitably lead the physical version of Ayyon to collapse.

The only thing holding him back is the Agreement. But the First's real plans are unknowable. Only one thing is clear right now. The First is waiting.
