Tende altum, volare altius
Very good guesses. There is no man in green, however, I have described what you need to look for already.I'm guessing that there's a fellow in a green cloak that we should be looking for. I'd also guess that we either need to dance or crack open the dance floor.
Edit: Re-reading the riddle, I think that the green fellow might be some sort of encounter after we silver the first part.
