ADVENTURERS
They are arcanists who joined one of the adventuring guilds and make a living by killing mana beasts and clearing dungeons. And they take other specific quests made by third parties, too. Also, non-Arcanists can be Adventurers if they have enough skills to fight mana beasts without magic (they were unheard of)
