DotMM Companion: Skullport


Welcome to another installment of the Dungeon of the Mad Mage Companion. This time we tackle Skullport, an optional and flesh-and-bones area of Undermountain. Unfortunately, it seems that Skullport was an after thought or a mark on a checklist for DotMM because it's downright skeletal. No quests are provided, and its recent desolation seems to be intentional so that less time had to be spent writing its chapter.

This supplement instead fleshes out Skullport, including the addition a major quest: to restore the Thirteen Skulls that once ruled Skullport back to sanity and topple the Xanathar Guild which recently put the Port of Shadows under its thumb. You'll also find:

  • DM Notes. Quick notes for the DM so as to not flip through the chapter.
  • Return of the Thirteen. A major quest, mentioned above, to walk back the Thirteen Skulls from the deserts of dementia. It's designed to be completed in one session and sends the adventurers to various locations through Skullport.
  • The Mad Mage's Visit. Advice on roleplaying Halaster Blackcloak when he visits his dear friend Tasselgryn Velldarn.
  • Areas of Note. Notes, scenes, and scripts for various areas of the dungeon.
  • Magic Item Descriptions. Save yourself the time of digging through the Dungeon Master's Guide to determine how the few magic items on this floor work. The appendix also lists the area the item is found.
  • Monster Stats. Statblocks have been prepared for all the unique NPCs used in Skullport, as well as any added in this supplement.

Made a map for the Grotto of the Netherese, and mentioned and linked the Companion to help you out! Love the Return of the Thirteen quest!

I need a standalone Skullport-based adventure for a group of six 5th level players. Would this work?

It would, but only as a one-shot that I estimate will take around three hours.

My party have just finished the Skullport arc you wrote, and I must say, loved it. Especially as they sent the only non-Undercommon speaker to negotiate with the kua-toa, inadvertently betrayed the Harpers to the Guild, and made the town guard cry.

You've brought so much more to this than 4 dry pages in the main book!

I love the skullport stuff! But I am sad there is no mention on the “crown of horns” artifact that was last seen in skullport

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
