From the campaign:
You've unlocked mountains of material for it, adventures, maps, expanded content, miniatures, 3d terrain and more. It is fantastic.
But we've added a little more to encourage you to spread the word and get your friends on board. We've updated the site with the new stretch goals but here they are in short:
20K Unlocks another Reaper Miniature
21K Christina Stiles joins the fray and pens an Highland adventure for pledges $59.00 and up.
23k We'll include players setting material in the Players Guide increasing that book to 90+ pages.
24K We go into the miniature business and use the orc lord who straddles the Highland and Aihrdian worlds as our starting point.
