The Abyss

No-Name guides them to The Abyss. Jopari explains that The Abyss was created when The Authority defeated the original Angel rebellion; he cast the angel leader into it to fall for all eternity. The Abyss sucks in all Dust which nourishes it and gives it its evil power.

As Lyra looks into The Abyss we hear Roger calling. He can see daylight.
