Willow was a mysterious reality-hopping traveler who encountered the Justice_League.

Steve Englehart used the character of Willow to continue the "Celestial Madonna" storyline he had written for the Marvel character Mantis_(Marvel). Englehart would later write a further continuation in his Eclipse Comics title Scorpio Rose, this time using the name "Lorelei". Both "Willow" and "Lorelei" are listed as aliases of Mantis in that character's Official Handbook of the Marvel Universe listing, which also gives brief descriptions of the events from the DC and Eclipse issues (while not using any terms trademarked to those companies).
