Guilds are official large-scale groups of hunters that raid Gates. Powerful guilds are considered to hold strength rivaling countries. In return for purchasing the rights to gates from the Korean Hunters Guild Association, they are expected to answer calls from citizens when requested. The leader of a guild is known as a Guild Master, most of which are S-Class. Guilds actively recruit high-level hunters with large sums of money as bonuses depending on rank. Hence, joining a large guild ensures access to a large amount of money and salaries, but is however accompanied by the risk of death in dungeons.
