The Videssos Cycle (sometimes known as the Legion Cycle) is the first quartet of novels that launched the Videssos Series: The Misplaced Legion, An Emperor for the Legion, The Legion of Videssos, and Swords of the Legion. The tetralogy details how a Roman legion led by Marcus Scaurus and a single Gaulish warrior, Viridovix, were transported across space and time to the Empire of Videssos.
