Since Mhaliah's map seems not to work anymore, you can find one here. This should work on ZMUD.
Caolin also has a map for CMUD which you can get from here.

Re: Map
For anyone who has made the switch from zMUD or CMUD over to Mudlet, I have been sharing updated versions of a Mudlet map I've created within the Kinslayer MUD Discord. Feel free to check in there and look through messages for it if you are interested in using it! If you know of anything I'm missing or see errors, please let me know and I'd be glad to update it and share again with everyone.
