These zones are all circle-based zones, with the stock circle format excepting one - Labyrinth.ZIP which has some added bitvectors in the wld, obj, and mob files. All were built by me - Kaan - my web page at dibrova.betterbox.net/~dibrova/ can verify that these are originals. All of these and then some are on my site, along with my email and MUD addy for any additional questions you may have. I hope these can be posted here.
