Kobold Press, chaired by Wolfgang Baur, has a track record of not only providing high quality content (like the Tome of Beasts, translated into German by the German D&D-publisher Ulisses Spiele), but also providing free content, including via their blog.
The campaign world for Kobold Press is 'Midgard', just like for Pathfinder it is 'Golarion' or for most of WotC it is the 'Forgotten Realms'. How and where can you as DM put the Kobold Press material on MYRA? That is what this blog post is for:
(At the time of writing this links to the files, entries and pages where you find the mostly free material:
- Who watches the watch-fires with stats for the AGE system, Free (I trust you're able to convert the stat blocks to the system of your choice).
- While this could be adopted in many places, including Gwynddor for the Ashcaran Dreamknights, I currently see that for Karcanon with the Great Wall of Bakanasan against the barbarians.
- The Death of a Mage Idea: For Hermund, Esoteria, Manablanda or Belfalas on Karcanon
