Launched in April 1995, Sovereign Seven was created by writer Chris Claremont and artist Dwayne Turner, and was Claremont's first professional regular series work since his departure from Marvel Comics and the X-Men franchise in 1991.

[1] The title met with middling success and was cancelled after 36 issues (three years), in June 1998, after which Claremont returned to Marvel.

The original group consists of Cascade, Finale, Rampart, Reflex, Indigo, Network and Cruiser.

Time portals open inside doorways to areas unfamiliar or well-known to the Sovereigns, who work as employees to earn their keep.

The coffee house is run by supporting characters Violet Smith and Pansy Jones, comic-book counterparts of the musical alter-egos of Emma Bull and Lorraine Garland—The Flash Girls—of whom Claremont is a fan.
