Hello Yochai, it all seems to have gone a bit quiet on this front recently. I'm looking to start a new campaign with my local dad's boardgame group and it seems that Cairn would be a good fit, is 2e available/going to be available to buy soon?
The player's guide is already available. You can get it from the Cairn website.
The pre-order store will be up very soon as well if you missed the Kickstarter.
