I must create a system, or be enslaved by another man's. I will not reason and compare: my business is to create.

Teratogenicon - the ultimate monster maker!

The ultimate monster maker is finally here!

TERATOGENICON - our most impressive book so far - is a collection of tables and essays on how to create your own monsters.

The book is beautifully illustrated by Rick Troula (of The Displaced fame). Take a look at the images below to see for yourself!

NOTE: There seems to be some issue with DTRPG's preview, making the index Table of Contents disappear. The PDF is fine, however, as you can see in the Quick Preview. Here is the ToC:

As you can see, Teratogenicon contains one chapter for each of the fourteen most famous monster types (aberrations, beasts, celestials, constructs, and so on). Each chapter examines specific habits, appearance, goals, traits, powers, origins, and many other topics. In addition, the appendixes will help you to create stats (for both old school and contemporary games), to roleplay monsters, and to include all monster types into a coherent whole, among other things.

The book is inspired by the most famous RPG in the world (in its current format and by its earlier "old school" version) but is mostly system-less. Use it as inspiration for ANY RPG of your choice, or even for your own stories, comic books, videogames, etc.

Print version: a print version is in our plans. However, it will likely take a long time due to current circumstances. If/When we make it available, we will send an email with a discount coupon to everyone who bought the digital version. If you want to receive this e-mail, make sure you're receiving e-mails from us, and change your settings if you aren't! Also, let us know if you need any help.

By the way, I've sent an e-mail to all our previous customers with a discount coupon - same for whoever is following our Facebook group. If you're a reader of this blog, I'd like to extend you the same courtesy. The coupon is good for 15 days:



  1. How does this compare with Raggi's Esoteric Creature Generator book?

    1. Well, I like Random Esoteric Creature Generator, it is great for crating truly random monsters and was certainly an inspiration.
      Teratogenicon is somewhat different, because it separates monsters by type (even though there are also "universal" tables). I compared it to the Appendix D of AD&D, that has random tables for creating fiends.
      Teratogencion has a chapter for fiends, but also Aberrations, Beasts,Celestials, Constructs, Dragons, Elementals, Fey, Giants, Humanoids, Monstrosities, Oozes, Plants and Undead.
      So, if you want truly random creatures, there are tables for that, but if you already know the type of creature you want to create - for example, an angel, ghost or android - you can find a chapter with that exact flavor.
      There are also specific rules for creating 5e monster stats (in addition to OSR), tips on role-playing monsters, etc.
      All in all, it is a lot more extensive.
