It seems while you have posted your data, the thread was moved or closed and your data cannot be posted. Sorry!
I also forgot to mention that if anyone can recommend books that would help out it would be great.
In English only?, just to clarify.
Have you googled it?.
There are lots of legends here in Poland, I am not qualified to tell them but I may be of service to give you key words to google.
The dragon in Wawel.
The sleeping knight in Zakopane.
The two brothers who built the cathedral in Rynek glowny Krakow.
The Mongol who shot the trumpeter with an arrow, while he was warning the town.
I don't know any books but I hope these help you.
