The official guards of the Sime~Gen Territory borders. Both the sime and Gen governments mount such patrols, but with different duties. The Gens patrol to keep the Simes from raiding out of the borders and to prevent newly changed-over simes from crossing in-Territory; the simes patrol to welcome such newly changed-over simes escaping the Gens, and to keep Gens from escaping from Sime Territory, or to keep Gens from raiding into Sime Territory.
