Getting there

This one is off the surface map — inside a dungeon, a cave or an upper floor. The way in from the surface is Wyrmscraig Cavern's: “Enter Cave” at tile 2530, 2205; the map, opened on it, draws that walk, and any teleport that lands nearer.

Nearby places

The closest other places with pages — usually a shorter walk than a fresh teleport.
