[NOTE: This map has been replaced by a newer version of the Yawning portal available here]

Because all good campaigns start in a tavern, right? 

The Yawning Portal. A renowned tavern, built around the remains of the mad wizards tower. For a small fee, Durnan is happy to lower adventurers down into the undermountain. A perfect start to Waterdeep Dragon Heist or Dungeon of the Mad Mage.

This map is my revised version for Dungeon of the Mad Mage. It is based on two more recent sources and looks a little different from older sources.  The two sources I used as inspiration for this map were the cartoon version found in DnDBeyond's source book as well as the upcoming terrain release from WizKids.

I've included all 3 floors shown, with spiral staircases connecting the levels on both sides.  I elected to keep it as shown in the sources and not add on any other rooms (despite this large inn missing lavatories...). I did try and solve the kitchen problem by devoting the top left side building to be a kitchen with warm light spilling from the kitchen inside, and a well warn path marked with spills as servers ferry dishes to and from it.

Hi! New Subscriber here. When I try to import the maps into Foundry with the .dd2vtt extension, Foundry says "Incorrect imagevideo file extension"

Hello, I cannot find the rest of the Dungeon of the Mad Mage series. Are they still available?

Riccardo Serafini

nice! I'm starting Dragon Heist with my campaign and hopefully we will do the dungeon next

Love this so much! I've only recently started Dragon Heist with my group, but we all adore your maps! Is there any chance you'll be doing some of the smaller locals in Waterdeep as well like Xoblob's or Mystra’s House of Wonder or maybe the festivals?

Thank you! I don't have plans for it in the immediate future - needed a bit of a break from Waterdeep (at least above ground) after 26 map releases. Not ruling it out in the future though.

Hello, I know this is a bit of an old post, but is there any chance of doing the printable map in colour? Love the work btw this is one of the best Patreons I’ve found in so long your work is awesome.

I'm noticing the the first floor stairs don't match up with the 2nd and 3rd floors.
