According to the kickstarter page of Conan 2d20 a Pict themed supplement would be published if the goals were reached. Unfortunately that was not the case but I’m still wondering if such a supplement or others are planned in the future. Does somebody know something about this?
I think that was Conan the Scout, where you can create Pict characters and where you can get more information about Pict society in general.
There is a bit on Pict society and how to make pictish characters in Conan the Scout but there was another supplement planned which was called Spear and Fang which would expand on Pictish society and character creation options. There was also another supplement after that which would be on secret societies but unfortunately the kickstarter didn’t receive enough money.
