Well I guess if you plan to use the upcoming Book of Taverns from Necromancer Games, you'll have to give some thought to where to locate some of these dives. The Witch's Teat (as in "cold as a...") is the newest preview from the upcoming Book of Taverns, slated to release early next year. The book will includes 10 new taverns for your characters to get thrown out of. It looks like Necromancer is going to be giving us lots of free previews in the coming months, so keep an eye on the page.
