Below is my map of Portown based on the snippets of information that Holmes provides in his sample dungeon in his basic rules. I’ve also added ‘Ajax’ Expeditions Unlimited’ from Holmes article ‘Warriors for Hire’ in Alarums & Excursions 11 (text at the Hall of the Mountain King). The street plan for the map was put together using Zak’s simple and excellent Urbancrawl Rules.
Key:
(1) Tower of Zenopus, (2) Thaumaturgist’s Tower, (3) Cemetery, (4) Sea Caves (dotted line is tunnel from Tower of Zenopus), (5) The Green Dragon Inn, (6) Palace of Lord Profane (father of Lemunda the Lovely), (7) ‘Ajax’ Expeditions Unlimited’, (8) Southern Caravan Route, (9) Ruined walls of ancient, unknown city.
Holmes also mentions catacombs beneath Portown but I’ve yet to decide where the entrance/s will be.
Anything that I’ve missed?
Cheers, Bogeyman

Very nice! You’re making some great contributions to the Holmes D&D scene!
Sorry, I forgot to mention that I have some Holmes material on my blog you might find useful: some new monsters for Holmes basic, as well as some revised wandering monster tables going all the way to level 9.
Fantastic – thanks Desert Scribe. That wandering monster table will be a great addition to Meepo’s companion. Now we just have to survive the first three levels!
