Publication history įollowing the publication of the role-playing game Shadowrun in 1989, FASA immediately followed up with the first adventure supplement Mercurial, an 80-page softcover book written by Paul Hume, with interior art by Joel Biske, Timothy Bradstreet, Barry Crain, Tammy Daniels, Tara Gallagher, Earl Geier, Rick Harris, and Jim Nelson, and cover art by Jeff Laubenstein. Soon it becomes clear that this is not a simple bodyguarding gig, as first a Yakuza gang and then a second group appears, and details of Maria's unhappy past begin to surface.
The Runners are hired to protect the rock star Maria Mercurial from her former manager, who apparently wants to harm her after she broke their contract.
