I really like to play using Cairn and having this supplement allows me to give it the right tone to play in The Old Word setting. I will be following closely the development of this project and if possible contribute to it.
This game is creative commons so you can use the content or add to it freely.
Ideally if you use the content you'd add this to it:

If you'd like to contribute in some way just drop me a message here and we can have a chat about what might work. There are a few restrictions, not because of me or the creator of Cairn, but because of the company that owns the game that is used for this game's inspiration.
