The Narn resistance during the Second Centauri occupation of Narn was organized by cells on Narn itself and off world, procuring weapons, food, and other resources. Former Ambassador G'Kar was the most prominent figure in this struggle, and indeed he came over time to symbolize not just the desire of the Narn to be free, but of all peoples in the galaxy. Remnants of the Narn starfleet not destroyed or interned by the Centauri eventually joined the struggle against the Shadows led by John Sheridan, the heavy cruiser G'Tok in particular playing a pivotal role in an early engagement in 2260. Once the Shadows ships' vulnerability to telepaths was discovered, they could be destroyed - thus the surviving Narn vessels were able to avenge their lost sister ships in some measure.
Narns also served with distinction on Babylon 5 by supplementing its security forces, most notably helping to repel Earthforce marines loyal to President Morgan Clark; as a police force on the station, they curtailed crime and even handled the local Centauri in an effective and professional manner. Consequently, while the Narn Regime no longer existed, the Narn remained a visible part of the struggle against the Shadows (and later the Vorlons as well).
