Note: Map of the Crossroads
This unsigned note was tucked into a bookshelf in the Crossroads, as if left for someone to find:
Do not stray from the marked paths. There are many mirrors. Some lead to danger. Do not linger longer than you must.
At the bottom is a crude map of floating islands, some of which seem impossible to reach.
