This is what I think of as a proto-event. It happened just before these sorts of things got branded and hyped as big events. If it had happened two years later, it would have gotten a "WRAITH WAR!" logo on the top of each issue and it would be a lot better known now than it is.
There were multi-part crossovers into both Avengers and X-Men as part of this event, and the effect of X-Men was much more long term and dramatic. The first appearances of Forge were split between X-Men and Rom, and the gun Forge used to strip Storm's powers was based on Rom's Neutralizer. So all the stuff that followed - Life Death, the romance with Forge, the years of powerless Storm - flowed from the Rom crossover.
ROM appeared all over the place.
Hulk #296, Avengers #244-245, FF #277, X-Men #185-188, Power Man & Iron Fist #73, Marvel Two-in-One #99...great stuff!
