The Cloudmarch Shelves

The nearest ring of floating shelves beyond Aelvyrenn's wards, still close enough that the Hanging Choir's writ carries and the Amber line's schedule reaches.

The Shelves are Aelvyrenn's near march: town-isles and delve-isles a short flight out, where the Choir's watch still means something and a lost traveler can usually flag down a passing zeppelin.
