A stable is a place where players may drop off or retrieve their pets. Stables are usually marked by a white picket fence, but some guild halls also have stables which may be accessed by standing directly outside them; at the entrance, near the sign for the hall.
viGilante constructed a Sextant-based Map of all Public Temples and Guild Halls, including information on the latter, which he posted in the Oberin Forum, General as "Noob Node non-Ghost Mapping Project." Including public stables.
