World of Aetaltis Update

We finished our latest round of public playtesting, and we're now well into the planning and development for the relaunch the crowdfunding campaign for the World of Aetaltis setting books! We still have a fair amount of work we want to do before we go live with this one, but we're very excited by how it's all coming together. The magic rules have been revised and expanded, we've added some great combat options, and the Amethyst Sea setting map is ready to go!

We've also just finished running through an internal playtest on a new set of Aetlatis adventures set in the region around Thornwall. Revisions are underway and a closed playtest is coming soon!

    Visit the Green Briar Tavern: Play-by-Post RPG Experiment

    Want to join us for an experimental play-by-post Aetaltis RPG experience? We recently launched the Green Briar Tavern, a new group on Facebook. The tavern is an experiment in online post-based roleplaying we put together. Stop by and check it out, or if you want in on the action, ask to join! We're already having a lot of fun!

    You can find the Green Briar Tavern here.

    If you'd like to join in, just ask to join. We're going to limit the number of players at first, but as time passes we'll expand the game.

    Our first book of Aetaltis fiction hits the shelves on April 12th! Discover a new world of adventure in this collection of pulse-pounding stories written by some of the greatest fantasy authors alive.

    Mechanical Muse Levels Up!

    Big news for Aetaltis and Mechanical Muse today! This announcement is going to have a huge positive impact on all future Mechanical Muse projects!

    The Inspiration for Mechanical Muse

    Mechanical Muse began as my personal dream. It is based on my belief that we can embrace the classic attributes of heroic fantasy, science fiction, cyberpunk, urban fantasy, and all the other beloved genres of geek culture, to create a universe that is both intimately familiar and totally new. All we needed was hard work, amazing people, and a supportive community of like-minded fans. We're off to one heck of a start! With two successful Kickstarters under our belts, one product already available, and upcoming contributions from legends of the industry like David Farland, Elaine Cunningham, Michael A. Stackpole, and Jean Rabe, the future looks bright.

    But I knew from the start that I couldn't do this on my own. Naturally we needed readers, gamers, and fans like you. After all, you're the reason we're doing this. What I also need, however, are partners and teammates to work alongside me as we strive to achieve our goals. After all, the task is too big for just one person.

    Presenting the Mechanical Muse Team

    Today, I am pleased to announce that I've found the team of amazing, talented people I was looking for. Allow me to present my new partners!
    • Art Director Mitchell Malloy (Riot Games, Fantasy Flight Games)
    • Layout & Design Guru Michal Cross (Achtung Cthulhu, Modiphius Entertainment)
    • Layout & Design Guru Shawn King (Legends Magazine, Ragnarok Publications)
    • Publicity/Marketing specialist Melanie Meadors (Ragnarok Publications)
    • IT/Web Admin Matthew Eberle

    • I am honored that each of these talented individuals have put their faith in this dream, and I can't wait to share all the amazing things we'll be doing! And of course, thanks to all of you, whose support and enthusiasm helped to get us here!

      Okay! Enough pomp and circumstance! We've got work to do. Talk to you soon!
