"On pg. 9 it says on a roll of 1 I can reach Corny Gron. Well, it's impossible to roll a 1 on 2d6, so it seems that I can never reach Corny Gron."
When you reach a mountain village, you subtract 1 from all further rolls for places in the mountains, so if you'll roll two 1's, instead of the Manor you reach Corny Groń :)
Polish theme is sparse, since the it's 20 pages-long game, not everything could fit. That's why Beyond Corny Groń was made on 300+ pages ;)
