Kzinti could manage, even letting them outrun and jam the news of each successive Kzin defeat. The first indication the Kzinti Patriarchy had that much of the Kzin empire was gone and that a significant percentage of all Kzinti had died was when human warships appeared in the skies above their homeworld. Meanwhile, however, on Wunderland, now liberated by humans, several surviving Kzin, led by Vaemar-Riit, the last surviving kitten of Chuut-Riit, and with the cooperation of Dimity Carmody, Nils Rykermann, Leonie Rykermann, and other humans began to cautiously cooperate with humans and try to learn human ways. Vaemar-Riit even enrolled at a human university and obtained a reserve officer's commission. These became known as the Wunderkzin, and some later proved to be human allies. This slowly growing Man-Kzin cooperation was bitterly opposed both by many other Kzin and by many revanchist humans on Wunderland, while others among the human and kzin communities on Wunderland sought to manipulate the situation for their own ends. There were also ongoing human situations - for example, Nils Rykermann, a Wunderland academic, in love with Dimity Carmody, married Leonie Rykermann, one of his students, during the occupation, believing Dimity to be dead. This situation has not been resolved. There was also a somewhat ambiguous growing relationship between Dimity and Vaemar-Riit; the two are depicted together on the cover of Man-Kzin Wars XI. The war ends in 2433 with the signing of the MacDonald-Rishaii Peace Treaty. The vast majority of the Man-Kzin Wars stories are set around the First War. "The Peace" Following the end of hostilities, the Human forces use their hyperdrive ships to initiate a blockade of all Kzinti worlds within range of Human space. The Kzinti of both their homeworld and the prominent colony of W'kkai begin researching hyperdrive technology in an attempt to break the blockade, with the High Admiral of W'kkai also hoping to overthrow the Patriarch. Due to the treachery of Ulf Reichstein Markham, the Kzinti of Kzin gain access to hyperdrive designs and an engineer familiar with them in 2438. During this time, the Kdaptist religion spreads among the Kzinti. On Wunderland, an attempt is made to form a stable, democratic government. On Earth, although no one seriously believes the Kzin will stay away, the ARM returns to its old habits of trying to eliminate all knowledge and technology of war.
