I am guessing from your nick, that English is not your first language? There are a few small issues of grammar, but they are not by any means serious. Just need a little more care

"I heard the Druids mourning strange words..." um, mourning should be murmuring?
"As still blindfolded and saw no danger" I was a little confused here...blindfolded means literally with a cloth over his face. Was he actually blindfolded or did you mean "blind to the signs of danger"?
The idea is great though. I would like to see you develop it further.
