Esoterica of Mars

Selected Option:
Softcover, B&W Book
PDF + Softcover, B&W Book

Abundant water! Rampant crime! Wealth and squalor beyond compare! And the best place on Mars to drink when you’re broke. Welcome to Vance, city of canals and chicanery!

Meanwhile, the exiled queen dwells deep in the Labyrinth of Night. She is Yazora, witch-warlord of Venus, and though she has built a cathedral city to her own glory, her very palace imprisons her. The heroes could free her, and her wish to travel Mars with them is sincere… but her power is unfathomable, and her courtiers love her too dearly to let her go.

Esoterica of Mars combines City of the Towered Tombs and Witch-Queen of the Shadowed Citadel into one convenient volume. No new material is added if you've already purchased those texts, but if you wish to hold the secrets of Mars in your hands, this volume is ready and waiting for you.


  • Archetypal Shakespearean characters to meet in the city, with full examples for each one.

  • New locations with characters and story seeds, including the Palace of the Prince and the looming presence of the Prison Spire.

  • Rival factions, with plot hooks for both their rises and their falls

  • New locations in the Labyrinth of Night and the Shadowed Citadel, each with characters and plot hooks.

  • A complete adventure featuring several factions with both parallel and conflicting goals, all set at a party to make Nero swoon.

  • The new Bond rules, attaching heroes to supporting cast and guiding the flow of the adventure.

About the Cavaliers of Mars RPG:

Cavaliers of MarsReturn now to dying Mars in its last age of glory. A world of flashing swords and choking sands, of winking courtesans and lantern-lit canal cities. Mars, where romance and heartbreak are two sides of the same obsidian chit.

Where lost cities are buried in the dunes, and dry oceans stretch out between the last daring bastions of civilization. Where the First Martians, the monument-builders, are but a faded memory. And the Red Martians have become decadent and capricious in their last days. 

Find yourself digging for someone else’s treasure in the lost tombs of Chiaro, or spitting defiance at the Roundhead priests of wild Ziggur, or dashing across the towered crypts of Vance with your long-lost lover. Lock steel with the Princess Invincible, even as your hand reaches towards your flintlaser for insurance.

Cavaliers of Mars includes:

  • A vibrant setting with cultures, careers, characters, and dozens of locations, all organized to get you right into the world of Mars!
  • An all-new system combining your character’s motivations, history, and beliefs with strategic swashbuckling action!
  • Astrology, crafting, psychic powers, and much more!

I had a question: these are supposed to be two separate adventures (or maybe an adventure and a location?, it's not very clear in the product descriptions) and some rules compiled together right? the exact same content, then why do each of them cost significantly more separately without this having some kind of offer?, I mean I'm glad to pick them up at a big discount but seems weird the original ones are not updated, thanks.

What game system is this for?
The blurb sounds like pulp sci-fi but the preview looks like fantasy

Cavaliers of Mars. It's pretty similar to CortexPrime toolkit, with a duel/project subsystems tacked on. For a typical check you have 2-5 dice pool vs. GM's pool of 2-3. Both sides pick the highest die (note that this from the more recent version of the PDF), and the person with the highest die narrates the outcome. This system can be used for fights, though a GM for high stakes clashes is advised to use a different one: it's like a paper-rock-scissors with dice (parries cancel lower strikes, stunts cannot be parried but their effect is indirect or modifies another strike, etc).

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.
