Xas Irkalla RPG by James Vail.

This book is from the 2017 Kickstarter campaign. It is a copy signed by the author and also comes with a signed art postcard. Sitting on the shelf since it arrived.
Dark fantasy and survival horror, the game is THE black metal RPG before that became more mainstream.
If you purchase this, I will try and find the digital content which backers got during/after the Kickstarter.
