Being from Scotland. I think a dragon is buried in the garden of Sterling Castle. 
Have you ever went to go look, I know dragons are suppose to be legendary creatures but I believe they are real and not just myths.
Yes, Where people think it's buried is a big mount of dirt. It's also said to the the place of the Round Table from King Arthur.
The enchanted world just may be real maybe King Arthur discovered it in the 1980s.
I guess. It's interesting to think about.
I believe the dragons was real  but I am skeptical on the fire spewing part. 
Do you think they were big birds? 
I do think they was birds they say they are suppose to be close in traits to reptilian and avian but I doubt it. What do you think?
