The Gray Prince
Jack Vance
 Schaine returns to Koryphon from school off-world, met by Kelse. They and Jerd are to meet their father, Uther, who has said he just learned something that is a splendid joke. Glissam agrees to visit Uaia with them. However, Uther is ambushed and killed by Retent Uldras. Schaine, Kelse, Jerd, and Glissam survive a similar ambush and reach the Madducs' domain Morningswake. Uther Madduc was exploring the Palga before he was killed. Jerd, Glissam, and Kurgech go into the Palga to discover what he found. After various encounters with the Wind-runners, they find the secret: an ancient temple built by Erjins, who are in fact fully sentient. They return to Morningswake, to learn that the Mull has ordered the land barons to give up their domain. The land barons defy this decree, and form their own Order of Uaia. Jorjol incites several hundred Retent Uldras to invade Morningswake. This attack is defeated by the Order's militia. A committee of the Mull arrives at Morningswake. Gerd escorts them to the Erjin temple, where he explains the first part of Uther Madduc's joke. The Mull has demanded that the land barons yield to the claim of the Uldras, who were there first. But the temple shows that the Erjins are sentient, which makes the Szintarrese slaveowners. Near the temple is the depot from which tamed Erjins are shipped. There they discover that the Erjin mounts and servitors exported by the Wind-runners are actually warriors, who at that very same moment are uprising and destroying their supposed masters. Erjin "servitors" seize control of Szintarre from its effete inhabitants. Erjin "mounts" turn on their Retent Uldra riders, but the combative Uldras defeat them. The Order of Uaia's militia (including Submission Uldras) fly south and defeat the Erjins in Szintarre. Returning to Uaia, they defeat a second and larger Uldra attack incited by Jorjol. This experience chastens some of the Szintarrese reformers, but the others persist in their campaign. Now Gerd Jemasze reveals the rest of Uther Madduc's joke. The temple shows that the Erjins were there before the Uldras, so they have an even better claim to the land. Furthermore, the temple's decorations depict Erjins arriving in spaceships and in combat with Morphotes: Morphotes are in fact the oldest inhabitants and "rightful" claimants to the land. Gerd, speaking for the land barons, tells the Szintarrese that to be consistent they should either revoke their decree against the land barons, or else give their own country to the Morphotes as well.
