Ancients

Extremely powerful NPCs, the Ancients are stronger than adventurers of an equivalent level. Members of the Thirteen Chivalric Orders, the Ancients serve as quest givers or as temporary allies. Each Order is in charge of overseeing one server. Most of the Ancients are the "heroes" of the Elder Tale subplot. However, by volume 7 of the light novel, most of them have been killed or sealed by the  monsters.
