In all seriousness, Yellow Dawn provides the best comprehensive, multi-era Mythos ruleset I’ve ever read [...]. It basically incorporates absolutely any Mythos era you’d like to play in: from Modern to Dark Ages to Post-Apocalyptic to Prehistoric, Near future to zombie invasion, heck, even to D&D or old Star Frontiers! I think that may be what you are looking for!

Quentin The Troll

Yellow Dawn has a lot going for it, and, considering it is independently published, is refreshingly professional and very well put together.

    Getting Started

    If you're brand new to Yellow Dawn then grab the character sheet, roll-up some stats, build some personalities and throw them into the grinder

  • Download a Character sheet: as included in the Yellow Dawn Primary Rulebook. Download
  • Jump into one of the free starter scenarios: there are a bunch of scenarios listed below, quick and easy to pick up they cover some key themes of the Yellow Dawn world
  • SCENARIO #1 - First Job: characters sign-up for a tour of duty with the CRC, City Recovery Corps and go on a Dead City Run. This is an effective way of bringing disaparate characters together into a team and gives them a taste of city life and the wilderness, and straight into the horrors of the InfectionDownload
  • SCENARIO #2 - Tough Gains: a quick one session scenario, based in a Living City, where characters are involved in robbery and revenge. It provides action and awareness of city life isolated from the horrors of the wildernessDownload
  • SCENARIO #3 - Wild Dog Gorge: characters are hired to hunt down a strange beast that is murdering people in this remote settlement. A great way of getting a new team of characters "on the road" and is an introduction to the cosmic horror of the Cthulhu Mythos. Download
  • SCENARIO #4 - School of Elemental Knocks: written as an introduction for characters interested in magick or becoming a Road Mage View
  • SCENARIO #5 - I'm a Survivor! Get Me Out of Here!: written as a team builder. Characters are thrown together in a “controlled” environment and strive to win the prize – but must face off rivals, and possibly each other in a situation that rapidly brings the true horror of Yellow Dawn into focus View
  • Peruse key aspects of the Yellow Dawn game system: a blog article discussing some of the USPs of the game and what makes it different from other RPGs of its genre. Although there are comprehensive combat rules included, Yellow Dawn focuses on drawing out the abilities of a character rather than the size of their gun. View
  • UTOC: United Table of Commerce (UTOC) is a global power with vast influence in the world of Yellow Dawn. Understanding what it is and how it operates can be useful for GMs and players entering the world for the first time. View
  • Grab some context: read a free preview of the first few chapters of the Yellow Dawn novel, Dog Eat Dog. It'll give you a flavour of the disparity between life in a Living City and the grim reality of surviving out in the Wilderness. Read Preview
  • post apocalyptic survivor wearing a gas mask
  • The struggle of post-apocalyptic survival: Brief article about how hardships lead players to push desperate characters towards considering crime or taking more risks. It’s a good case in point, that keeping the characters poor and hungry for the first few sessions really builds up the tension of survival. Read article
  • Scenarios

    Some small items to get your game going. Ideally you can drop almost any kind of scenario from other RPGs into Yellow Dawn.

  • Red Desire ¦ Cold Murder: a small scenario that starts in the Living City of New Tokyo and takes the characters into a defended enclave within the Dead Zone there. Drug dealing, gang turf wars and some seriously tough moral choices. Suitable for three or more characters, with a Living City background or access to modern technology and weapons. Preview/Buy
  • Baruch's Burden: a small scenario that can begin in any Living City or any wilderness settlement with transport links back to civillisation. The characters are hired as cheap labour to help support a "tourist" expedition of the wilderness; but the itinary goes sharply awry after an encounter with a group of local Orcs (The Changed). Suitable for two or more characters with Wilderness backgrounds. Preview/Buy

    What is the Wilderness: A Definition

    Guidance that can help shape your early games

    Following the event known as Yellow Dawn, distorted weather patterns and the alien meteorological phenomenon of Storm Curtains (resemble the ghostly and enchanting aurora borealis except are a dirty amber in colour) are responsible for planet-wide disruption to digital satellite communication systems.(!) How much disruption is down to the GM and creates the pivot point for scale of isolation the GM wants for characters in their game.(!) As is the distance between survivor settlements when out in the wilderness. Read this brief article to see examples of how GMs can adjust their game to suit the flavour they want for their player characters. Read article

    This bolt-on for the core Yellow Dawn system demonstrates the way in which the Infection has been designed to evolve within the game. In other words, the things survivors mistakenly call "zombies" can change as time goes on, creating further drama and intrigue about what is really going on and intensifying the horror.

    Take Yellow Dawn 10,000 years into the future. Several decades after the apocalyptic event called Yellow Dawn struck Earth and ushered in the Age of Hastur, the Mythos arrived in force. Wars raged. Temples to the Great Old Ones and Outer Gods were erected by the monsters that worship them, puncturing the Quantisphere and leading to humankind being pushed ever closer to the brink of total extinction. Skip 10,000 years into the future and the human race has survived and evolved to a point where life is almost medieval. New races exist and the horrors of the Mythos remain as a fact of daily life rather than lurking in the shadows of denial. NOTE: this is very much still just a concept in development. Take a peek and let me know what you think.

    Client Testimonials

    • Complete package - an amazing roleplaying game.

      Hagen Landsem
    • What is great is all the resources available in the book for running campaigns, in such a way that you only need a rough story line, and use the system to roll yourself through it. NPCs, scavenged items, settlements, spells, vehicles, weather... its all there to be used to enhance the atmosphere and details of the story. I highly recomend this book for all cthulhu players.

      Chris Halliday
    • There's a great way of generating quick adventures called 'Dead city runs' which can be set up and ran in an evening without any preparation - kind of like very involved encounters or mini dungeon crawl.

      S. Pyne.
    • I had no idea Yellow Dawn even existed and the core book and the supplements are a great read. I recommend it to anyone looking for something that is kind of equal parts post-zombie-pocalyptic, more cyber less punk, and Mythos.

      Vargr, RPG.net
    • I became interested in your Yellow Dawn setting, and decided to purchase Dog Eat Dog. Just wanted to touch base and let you know that I thought it was a FANTASTIC read. I’m really looking forward to the Yellow Dawn setting book arriving in a couple of days, and giving the setting a run.
