This one succeeds on all counts-it successfully blends elements of high fantasy, superhero tropes, and science fantasy, serves as a set-up for events to follow, and is an entertaining mini-adventure in its' own right. While a bit linear (as might be expected in a scenario of this length), ambitious GMs could certainly expand on the options given inside. Though I'd normally give this one a four star rating, the spectacular cover artwork puts it over the top.
