Ancients

Extremely powerful NPCs, the Ancients (also known as the Precursors) 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.

Overview
How the Ancients came about is a mystery, with only several theories behind them. All that is known is that they first began appearing when Landers in the continent of Eureddo (Europe) traveled to the Land of Wen (America). Despite the presence of Demihuman monsters even there, because of the Landers' faith, the Ancients were "born".

However, not even the superior power of the Ancients were able to completely stop the monsters, since the monsters would simply respawn over and over again. Because of this, the Landers used a spell that summoned Adventurers.
