I read it twice but it is not clear to me how these adventures are really connect together.

Not really in the open question free form spirit of DW. Ask the players questions but basically crowbar them into the concrete adventure. Lots of magic items which basically circumvent the dangers too easily and the stories fail to fit together very well. Very disappointing for the price.

The artwork is lovely though!

I find this a rather good adventure, but which would benefit from a slightly stricter approach and more stringent language.
