As I grow older, I wonder what legacy I will leave. What have I done, or could I still do, to make things better for those who come after me? When I'm seeking inspiration, all I need to do is think of my friend Esyllt Harker. Esyllt was a beautiful and respected voice in traditional Welsh song and story, or chwedleua. She passed away 10 years ago, on 31 May 2014, but remains a strong presence in the world of storytelling in Wales.
