Prologue - The King of Thea

I'm still learning English, so I'll be happy to receive suggestions to improve my writing. This book is a draft and can undergo severe alterations at any minute. To be finished you must tell me what do you think about the story. Even if you can't get through the first chapter, say it in the comments, that helps a lot. There is not always a guarantee of a happy ending, but stories always find a way to continue. The Kingdom of Castela was one of the ancient kingdoms of the Iberian Peninsula, in 1230 Ferdinand III the Holy received from his mother Berengaria (in 1217) the kingdom of Castela, and from his father Alfonso IX the kingdom of León, unifying them in a single realm of León and Castela. This story is more about new year than any of that. It takes place in the mid-1600s,  in a fictional kingdom called Castela on the fictitious island of Kreg located in the north of Europe. Now let's see what this place has got and so special!
