Yeah. I have hard time finding due to lack of real source. But I read on several placed that Poland has/had
some. I came across a book from
Louis Léger who writes about it. It has plenty of information and I think it's quite decent, explains a lot of stuff, although not a fun-book in a sense it's entertaining, but more like a study. Still, I found it very helpful. But it's really a huge pity as I think it's very interesting. Thanks for those links. I did read plenty, still searching for some.
By the way, I had a comedic take on Morana when I was writing a short story. It was picked among 20 best so it will get published this year probably.
