Lerris is a town of mixed Ledomaritan / Xonan population, situated on the far west of the Xonan continent, near the border. It is the home of Kera's first foster parents. Most of its inhabitants were killed by Enforcer Shell in a maniacal spree intended to lure out Rainbow Dash for a final confrontation. The psychological effects of this massacre were felt for several books afterwards, most notably affecting Kera, Belle, Pilate, and Rainbow.

After Elma left the group to pursue her dreams, she decided to change her name to "Lerris" to signify moving away from the past and finding a fresh start on life.
