Whatever your fictional world, there should be a sense of its past and oral story telling is one way of preserving that. So in your world, what is the importance of story telling in general and the oral tradition in particular?
In my Fairy Kingdom the villages and other settlements have annual shows and oral storytelling is a major part of this. Stories are re-told and even acted out. It is considered vital the classic fairytales are well known by all.
And yes stories get written down too and put into books.
So what forms does story telling take in your fictional creation?
