Diferentes romances da UE apresentam destinos potenciais para a União Cardassiana.
As referências mais óbvias são " A Stitch in Time " de Andrew J. Robinson (o ator que interpretou Elim Garak). Nele, vemos que Cardassia Prime sofreu enormes perdas de população e infraestrutura, com quase todas as grandes cidades tendo sofrido ataques catastróficos do solo e da órbita. O governo está sendo reconstruído em linhas democráticas (com alguém chamado Alon Ghemor à frente de um movimento conhecido como o Projeto Reunion ). No final, vemos que o planeta está começando a voltar a uma aparência de normalidade.
"Someone once said that democracy was the flawed solution to a perfect mess . . . and I absolutely agree. The Reunion Project won a majority in four of the six sectors, and instead of being able to impose their will on the political situation, everything is discussed endlessly . . . and then put to yet another vote! Is this your vaunted democracy, Doctor? To be subjected to the opinion of any person who has the breath to utter one? How does anything get accomplished? If this is—as some fervently believe—a Federation plot to diminish Cardassian involvement in the quadrant, then it has succeeded ingeniously. We’re much too involved in discussions over power grids and waste disposal to care about anything else."
Você também tem o destino muito mais sombrio visto em Millennium: Inferno , no qual o povo Cardassiano sofreram nada menos que sua completa e completa destruição:
"The survival of Cardassia?" Cardassia's defeat was the gravest event Garak the tailor could imagine. Nothing meant more to him than his world and his people, despite the flawed leadership that currently blighted both.
"Even graver, I'm afraid," the visitor replied. "Though I have seen … I have seen Cardassia Prime laid waste and our people … our people erased from existence."
