Kunie

The Kunie are factions in Theldesia that maintains the magical technology left behind by the Alv. As a result, most of them, or at least their leaders, are Half-Alvs.

Overview
The Kunie are a mystery; while their existence is known, who they are and what they do is largely unknown. Members of the Kunie clans are secretive, and ReGan states that previous Sages of Mirror Lake had attempted to contact the Kunie to no avail.

As the maintainers of the Alvs' legacy, the Kunie are the ones maintaining the Bank system, and are in charge of watching the infinite pool of gold that provides the server with the gold that is carried by monsters. It is mainly for this reason that they stay hidden from the public -- if it was known that they were protecting such technology, they would be viewed as traitors to the Landers by "supporting" monsters.

It seems as though the Kunie are not one united faction, or even branches of the same family: Yamato has two Kunie groups, one in Eastal (供贄), and one in Westelande (久爾永).
