Ron Marz, Tom Grindberg and Tom Palmer begin a four-part story running through the Superman books this month, in Action 749 (Dec. 98).
Lois and Clark are walking by the Hypersector construction, and are surprised to see a blimp landing post. And even more surprised when Superman has to fight an alien near it.
The architecture of the building resembles those from Kandor, and Superman hunts out Scorn, who recognizes the building, and communicates with the Kandorian, learning that he has no idea what sent him out of the bottle.
They head to Emil Hamilton, who uses his Kandorian viewer. They see that there is some sort of unrest in the city.
They all head to the Fortress of Solitude, where Emil sends Superman and Scorn into Kandor, as well as Ashbury, who refuses to be left behind.
The story continues in the next issue of Superman – The Man of Steel.
