A Path-Weaver is seldom seen whole. It shows as a long, thin shape moving inside the stone, a ripple along a wall like something swimming under ice, and when it surfaces, a narrow figure of grey stone threads with a dull orange glow, long-fingered, faceless. Its fingers trace lines on the rock, and the rock follows them. The sound of its working is the Maze’s sound made small and close: clicking, like locks turning, and a soft grinding.

They live within the walls themselves, moving through them, and are found throughout the Maze, though rarely.

They are restless and curious, and they weave paths for the pleasure of it. They seem to follow travellers for a while before deciding what to do with them. Calm travellers who go with the Maze’s shifting often find a Path-Weaver opening the way ahead; frightened ones find the corridors narrowing, as the Maze itself does to fear, and a Path-Weaver pressing the change along.

They open and close corridors, link one passage to another, and can shut a chamber completely or open a door where there was only rock.

A favoured traveller gets the shortest way out of the Maze. The danger is a closed corridor with someone still in it.

Those who have come out of a Maze tell newcomers to thank the walls when a way opens, in case a Path-Weaver is listening. It may be.
