Aetrimonde

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.
