The Purge is a special combat unit ran by the Arite Family. They are elites that are excell in combat and survival and they are highly respected. The purpose of this division is to keep peace under the Shield of Aegis safe from the Tainted and to explore ancient ruins that were left after war. Even though they could be classified as an army, they are not treated as such. There is no use having an army because there are no outside threats that could launch large-scale attacks on the Lands Under Shield, because the Shield of Aegis is unconditionally protecting people under it.
