From the publisher's blurb:
Axioms is Autarch's quarterly supplement for the Adventurer Conqueror King System. Each issue of Axioms offers a mix of short content updates for ACKS, such as new classes, new sub-mechanical systems, explorations of specific themes within the game, short adventure scenarios, and more.
In this, our second issue, beastmen, the savage swords of chaos, are unleashed...
A Culture of Battle: an overview of the history, social structure, familial relations, economy, and language of beastmen
Domains of Chaos: rules for beastman clanholds, chaotic domains, demographics, and tribal warriors
The Weapons and Warriors of Woe: variant beastman arms, armor, and leaders
Bred for War: creating custom classes for beastman PCs and NPCs
Who Stands Against the Beastmen?: an overview of the Auran Frontier defenses
While designed for use with ACKS, content in Axioms is compatible with any d20-based fantasy RPG built on the OGL.
Axioms is made possible through the support of our patrons, who receive early access to the articles on a month-by-month basis. If you're already a patron, thanks for your support! To learn more, visit https://www.patreon.com/Autarch
