The day before I went to make a video about Dinas Emrys, which is a hill in north wales near Beddgellert which is renowned as Merlin's Castle and where the Red Dragon of Wales is reputed to be imprisoned and where Merlin's Gold is waiting to be claimed by a fatherless child!
Dinas Emrys is where the trilogy begins and ends. When I was planning and writing there books, I gained such a visual impression from my researches, that I decided not to visit until I'd finished the series. This week was my first chance... but it was pouring with rain. I'll have to visit another time - maybe on the Eve of May Day - the night when dragons traditionally fly and fight each other!
