Wisdom leads a team of MI-13 agents to stop hostile fairy incursions from Otherworld and the story goes bonkers from there. He gets help from another British agent, Shang Chi.

Lots of fanciful stuff along the way, including several alternate-reality threats, nightmares, a martian invasion, and the return of Jack the Ripper.

Oh, and The Beatles. (They’re skrulls.)
In order to stop the madness, Wisdom has to shoot his girlfriend in the back. That and the fact that there’s lots of swearing solidifies that this is a MAX title.
The problem with MAX titles is, it’s never clear whether they’re canon. I don’t see any major reasons why this couldn’t be, but I acknowledge it doesn’t fit cleanly into continuity as far as I can tell—but please feel free to drop a comment and educate me. It might take place during the period where Captain Britain gave up being king of Otherworld and joined up with Excalibur, and there are references to Wisdom having once dated Kitty Pryde. In any event, most of it appears to be distortions of reality so none of it really matters anyway.
Paul Cornell is a fine writer, I’m just not all that into these “fantasy-based” stories. It’s good enough, though, and holds together despite a new artist joining midstream—never a good sign for a continuous story.
