Foreign Legion

Man-Kzin Wars XII Short story by Hal Colebatch and Matthew Joseph Harrington, published in Man-Kzin Wars XII (2009).

The Jotoki unleashed the Kzinti on the universe by employing them as mercenaries. Later they "recruited" a Roman Legion from Earth to help in the fight against the Kzinti. Centuries later, the descendants of that legion (and the Jotoki who brought them) are discovered on a distant Kzin colony world by a human who wants to bring them home.
