Zealot

"Zealots? Well, wow. Look at them. They look so cool that they're all monks. Monks of the Erathian freaking Union. Well, it seems they seem to be nice about this..."

--Su Ji-Hoon, Zealots of War

Zealots are master monks that serve for the Erathian Union. They use magic attacks and prayers for angels in their monasteries, even in the novel.
