Dhakos, The City of Spires - Watabou Cities Annual
I wrote an adventure, more of a scenario seed really with an encounter map and some bad guys, awhile back that was for Mongoose's, Elric of Melnibone RQII. It was originally pitched to go in their Signs & Portents magazine but unfortunately the magazine got canned before I received a reply. I ended up self-publishing it, changing the names of things to avoid any legal issues with IP infringement. Anyhow, there is a fan site, Strombringer.com, where I may be able to publish the adventure as originally written.
I've re-drawn the commissioned encounter map but I want to draw the city, Dhakos, Capital of Jharkor and I'm after ideas on how to do what's in the title. A description of the city buldings says they're square or rectangular with central gardens, have low square towers in each corner and a spire connected to each tower overlooking the garden.
The tower isn't a problem - I just add another sheet above the Buildings sheet and apply an approriate wall shadow effect but how to do the spires?
