"There are lots of them! I actually started hanging around with Tony and Bella and Sherlock when the latter two rescued me and Tony from some wizards who were keeping us prisoner in the Cave of Unpleasant Surprises, which I had of course walked right into. With entrances that are often within the forest, there's the Caves of Fire and Night, and the Caves of Chance, and the Caves of Sunless Gardens, and the caves that magically refuse to have any name attached to them. There are fewer farther away - this is the highest concentration of place magic - but I wrote a thesis on the Caves of Irregular Dimensions once, years ago, that's nowhere near here."
