Here’s a story which you need to be able to put aside logic in order to enjoy. And there are things to enjoy in this story, as long as you don’t mind your favorite character being marginalized in order to make the Substitute Legionnaires look good. ‘Cause, believe me, with the possible exception of Colossal Boy, no regular member of the Legion comes out of this story looking good.
A bellicose planet called Throon begins using force rays from a deadly citadel (The Citadel of Doom!) on the planet’s surface to cripple spaceships. They cripple any ship which passes within 30 Million Miles of their world. The Science Police lament that this will cripple interstellar commerce, and, indeed, we are shown planets in the galaxy where children ask why there is no food, and parents say because no one can deliver food to us via space travel.
