He is the advisor of all residents of Narshe, and runs the Narshe guards. He believes that the town should stay out of external conflicts, as it is a coal-mining town, and providing either the Empire or the Returners would draw them into a bloody war. This desire is threatened when the townspeople dig up a frozen Esper in the mines, drawing attention from both groups.
When Banon, the leader of the Returners, confronts him in person, the Elder still refuses to participate, but accepts the help of the Returners in protecting the town from an Imperial attack lead by Kefka.
After the Returners raid the Magitek Research Facility at Vector, they return to Narshe to find the Elder and the town have accepted the inevitability of war and agreed to support the Returners in a joint attack on Vector.
It is unknown what became of the Elder in the World of Ruin, but as Narshe is overrun with monsters he presumably was killed or fled the town.
