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.
This issue is a special edition, published in between our 3rd and 4th issue, to thank all of our ACKS fans by giving them more content!
The articles in the Special Edition issue are dedicated to long-term campaign play, with rules that provide a structure with which campaign activities each month can be handled as systematically as ACKS handles actions every combat round and exploration every turn. They cover:
Divine Activities: everything you need to know about acquiring and using divine power in campaign play
Domain Activities: mechanics for administering domains, inspecting troops, and more in campaign play
Magical Activites: everything you need to know about researching and crafting spell
Mercantile Activities: new-fangled rules for seeking profit the old-fashioned way in campaign play
Professional Activities: mechanics for crafting, training, and other specialized labor in campaign play
Syndicate Activities: mechanics for making crime pay and punishment go away in campaign play
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
