I can’t meaningfully contribute to your Wilderland-specific woes. I can only chime in with my usual counterexample to the question of whether any published adventure serves as a good teaching tool for its game: Eyes of the Stone Thief for 13th Age.

13th Age strongly promotes a hand-wavey spirit towards its rules, so any rules inconsistencies between Eyes and the 13th Age rules would probably be shrugged off (or even embraced) as “lazy development” by all authors involved. Or maybe they’d consider it “laissez-faire” development?

But one of Eyes‘ unquestionable strengths is its organization and presentation that do their best to make sure you run a kick-ass 13th Age game. Gareth Hanrahan, the author of Eyes, always seems to have the 13th-Age-specific rules and setting information in his head and he makes a real effort to keep them in the foreground when possible.

I believe that Eyes’ massive size (300+ pages) is the biggest hurdle to wider recognition of all of the things this book does right.
