This will be part of a larger upcoming release, The Wayfinder Foundation’s Register of Extraordinary Individuals, containing 12 Eberron sidekick archetypes and NPCs, hopefully to be completed in 2-3 weeks
This looks amazing!
If I get that right, they work similar to the sidekicks from the essentials kit, making it possible to run a one or two player ebberon campaign?
Can you tease other potential sidekicks?
Yup, you can run them like an Essentials Kit sidekick. My design philosophy was to make my sidekicks a bit more powerful than those in the Essentials Kit, though. You can also use them as custom Eberron NPCs in traditional games with more players, or as temporary allies. The applications are quite broad.
I can tease you the archetypes that will be in the supplement. There will be 12 archetypes, roughly sorted into four categories.
