Your Journey from Adventurer to King Begins Now!

Enter a world where empires totter on the brink of war, and terrible monsters tear at the fragile borderlands of men; where decaying cities teem with chaos and corruption, nubile maidens are sacrificed to chthonic cults and nobles live in decadent pleasure on the toil of slaves; where heroes, wizards, and rogues risk everything in pursuit of glory, fortune, and power. This is a world where adventurers can become conquerors – and conquerors can become kings.

Will you survive the perils of war and dark magic to claim a throne? Or will you meet your fate in a forgotten ruin beyond the ken of men?

  • Run a thieves' guild and send your minions to carouse, smuggle, steal, and commit other hijinks.

The PDF appears to be coming out blank. Is this a known issue or is the problem on my end?

I recently purchased the pdf/combo of the ACKS main rule book through I am extremely disappointed with the quality of the printing. The paper is thin, flimsy and see through. Very cheap feeling. The print and tables are look like they were printed on home office inkjet a printer running out of ink, they are muted and hard to read. The hard cover binding is fine but the paper and printing is just awful.

I regret paying a premium price of $30 for this product.

In the current version of the PDF there are issues in the Monsters chapter. Specifically, the images (e.g. Elf, Gnome, Ghoul) cover up text. Is it possible to correct this? Thank you in advance.
