From the author

Dear Game Master,

I have been running D&D and other TTRPGs for more than ten years.

Constructs were the monsters my players remembered least. A golem stands in a room, hits hard, shrugs off a few spells and falls over. Nobody at the table asks who built it.

So I wrote a bestiary where every machine has the same maker. The Ironveil Order is a secretive cult of artificers, disgraced wizards and heretical clerics who replace flesh with clockwork, and each machine the party breaks tells them a little more about who is building them.

The book is made for 5th Edition and built on the SRD 5.1.

  • 6 automatons and servants, CR 1/4 to 3, from the spying Clockwork Beetle to the Fleshbound Homunculus
  • 14 war machines, CR 3 to 9, from the Cogwork Stalker to the Arcane Ballista
  • 10 ascended forms, CR 10 to 20, from the Essence Harvester Titan to the Mechano-Lich
  • 30 sets of lore, tactical notes and a weakness, one for every creature in the book

I hope the Order gives your players someone to be afraid of. See you on the Order’s trail.

P.S. To bring the Order into your campaign this week, start with the Adventure Hooks in the Introduction: clockwork vermin stealing small metal objects near a village.

I create the characters, places, and visual moments that give each book its own personality. My goal is to make every illustration feel like a small window into a world you’d actually want to explore.

I edit every book, fixing grammar and word choice while keeping the author’s voice, so the text reads clearly without losing its character.
