The Gatewatch/Visions and prophecies

The story of the Gatewatch was mapped out in the Bolas Arc. This allowed the writers to weave in some visions and prophecies that would come true in later chapters. It is expected that eventually all elements of the prophecies will come about.

Nissa's visions

On Amonkhet, Nissa Revane experienced several visions sent by Kefnet in The Hand that Moves.

A dark snake, winged and venomous, cast its shadow upon the desert. The snake was huge, bigger than an oak, bigger than a forest of oaks. Its shadow covered the whole world.	Nicol Bolas, arriving on Amonkhet, as the Mending approaches.
