Heroic Roleplaying in a World of Swords, Sorcery, and Steam

I’d like to introduce Aetrimonde, a TTRPG I’ve been designing with heavy inspiration from the houserules my group used back in our Dungeons and Dragons 4e days. I’m not ready to publish Aetrimonde yet, but I’m opening up this blog to discuss its design principles, mechanics, and systems.

Posts about Aetrimonde’s titular default setting: regions, cultures, magic, etc.

  • Keeping on with October’s theme of mad science, today I’m going to cover one of the fun aspects of Aetrimonde, and something that lots of players might aspire to command in a campaign: airships! Broadly speaking, there are four kinds of flight available to PCs in Aetrimonde: Flight magic letting a character fly under their…

  • It’s a little bit early, but today I’m kicking off this year’s Halloween season of the blog. Last year, I expounded at length on the undead, as part of introducing the basics of how Aetrimonde’s monsters and enemies worked. This year, I’ve got a different topic: mad science and occult magic! Both mad science and…

  • I recently wrote about failure modes and what a GM might be able to do if an adventure goes awry. One of those things is resurrection: bringing back a dead character so that they can still participate in the adventure. Today, I’m going to go into more detail about how that works in Aetrimonde. The…

  • Today, I’m going to continue my series on Aetrimonde’s alcohols, ordinary and unusual, with a discussion of wines: Imperial Purple: The Novan Imperium, like the Auran Empire that came before it, has a long history of winemaking, and wine is the alcoholic drink of choice in the Imperium even today. Sadly for the Imperium’s urban…

  • I’m slowly working on a post that will go into more detail about the titular spirits that grant powers to Spiritual classes, but the title “Spirits of Aetrimonde” put an idea into my head that has been hard to get out. So today, I’m presenting the first in a series of posts examining Aetrimonde’s cultures…

  • If this post is taking a while to load, or you have a large chunk of whitespace in it, not to worry! It’s because today’s post features a map of Aetrimonde, in what may be overly high resolution. It’s going to be a short post today, although I’ll mention a few pieces of worldbuilding that…

  • Today, I’m going into more detail about the Unclaimed Reaches, homeland of Ipki Chainbreaker, the goblin Inquisitor who I’m building as a fourth sample character. The Unclaimed Reaches aren’t one of Aetrimonde’s major polities (in fact, they’re not even a minor polity…), so they won’t be getting the full two-parter treatment like the Dwarven Federation…

  • In today’s post, I’m going to go into more detail about the deity Deum Radiant and the Illuminate Society, one of the many sects within this deity’s faith. Both of these concepts were introduced in my recent post on Ipki Chainbreaker, goblin Inquisitor. This content won’t be a part of the CRB when it releases,…

  • Before I get back to building the latest Inquisitor sample character (and if you haven’t already voted on their ancestry and faith, go do that now!), I’m putting up this one last post related to faith and religion in Aetrimonde. Today, I’m talking about the heavenly realm! …Which means it’s going to be a short…

  • Following on from its mentions in my previous post, today I’m going into detail about the “antechamber to the afterlife,” the Underworld. This is another of the alternate planes of existence that overlaps Aetrimonde; for more details on Aetrimonde’s cosmology, see this other previous post. Aetrimondean cosmologists often treat Faerie and the Underworld as related…
