In the title story, we meet Marvin the Dragon—still a pup with his Mom but make no mistake, both are formidable. Their ferocity catches the eye of the Keeper who is still making his way up the ladder in Antipolis and has many dangerous enemies. He makes them his bodyguards. Soon enough, crafty little Marvin manages to witness a sinister plot and tries to save the Keeper and the city's leaders from annihilation. In "Soldiers of Honor," Gork and Krag are brothers and soldiers of hell. They keep a secret door in the Dungeon. The door being little used, they get bored, until an old blind man forces Krag, alone on duty that day, to call reinforcements to prevent him from entering. Because he has not fulfilled his mission, Krag is sentenced to be killed by his own brother in the middle of the desert.

The last two stories of Dungeon!

In High Septentrion, there has been a violent eruption on the planet of Terra Amata. It’s a scramble to find breathable air, but the wizened blind, mystical dragon the Dust King (Marvin) thinks that it is perhaps time for him to die heroically. However the feisty young Marvin the Red refuses to give up and plans to find a way out of this mess, including finding a way to actually breathe… Art by Alfred of Why I Killed Peter.

And in The End of Dungeon the more the islets of the planet Terra Amata move upward, the less there is of breathable oxygen. While Marvin the Red and Zakutu, daughter of the Grand Khân, attempt to protect the seven objects of Destiny, Herbert and the Dust King are forced to swear allegiance to the Dark Entity in order to gain access to breathable air.

All things must come to an end and so it is with the great Dungeon.
