Of Mercanes and Megapedes, a Spelljammer Adventure


Of Mercanes and Megapedes


In the shattered and violent system of Doomspace, rapacious pirate factions vie with one another for the favor and patronage of the mercane arms dealer, Vocath. When would-be heroes from a distant system appear seeking his help to build an alliance, the shrewd powerbroker sees a unique opportunity. The price of Vocath’s influence is small—collect on an outstanding debt. But what will the heroes do when that small task becomes lethally huge?

A Spelljammer: Light of Xaryxis Expansion - What's this all about?

In Light of Xaryxis, chapter 8, “Arena of Blood,” after rescuing Warwyck the giff in Doomspace, the party seeks an audience with Vocath the Mercane in order to unite a group of factions into a coalition against the astral elves. In the book, Vocath proposes that the party participate in a pit fight in order to garner favor with the spectating factions. While the premise of an arena pit fight is certainly exciting, this supplement offers an opportunity to add further complexity and nuance to the relationships between Vocath and the factions. On this quest, the party explores a new small “dungeon” location, Katch’kaht (catch-CAUGHT) XI, with exploration, a bit of mystery, and some high-stakes combat. 

This adventure provides a personal quest on behalf of Vocath such that he feels indebted to the party and has a stronger motivation to help them achieve their goals. The adventure also ties in another one of the factions, to make the negotiations in chapter 9, “Discord and Diplomacy,” carry more weight. 

As always, it is up to you how much of the content you want to use. It’s perfectly fine to use some parts of this supplement while discarding others, or simply let the ideas presented here inspire new ideas of your own. This supplement assumes a party of four to six characters of 7th level.

This Adventure Includes:

  • Combat. Spelljammer denizens and an epic megapede with lair actions!
  • Exploration. Discover what happened to the thri-kreen in their asteroid base.
  • Social. Enchance Vocath's role in the campaign and perhaps befriend an eye monger along the way?
  • Color VTT-Ready Maps. Explore the asteroid Katch'kaht XI floating in Doomspace.

Adventure Summary

Vocath makes a deal with the party: they recover megapede eggs for him, and he will use his influence on their behalf to get the faction leaders to meet. 

When the party arrives at the asteroid, Katch’kaht XI, they must search the surface to find the hidden hatch entrance. Once inside, the party must contend with a hungry eye monger named Bloatdust. In the aftermath, the party can find clues about an accident with the megapedes and some equipment. Later, the party discovers that the asteroid base has no spelljamming helms and can be taken over. In the next room, the party can find more details about what happened at the base, discovering empty canisters that were used to house the megapede eggs. 

A pair of large cargo hatches in the floor leads to a massive storage bay below. Hidden under the rubble and debris is the last remaining megapede, fully grown, carrying a sticky clutch of eggs on its back, and violently hungry. The party must find a way to retrieve Vocath’s eggs and survive the experience.

Rules Edition(s)
Original electronic
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.
