Adventurers' Guild

The Adventurers' Guild is an international organization that has various branches in the cities of many countries throughout the world. Each Adventurers' Guild location has a Guildmaster.

The Adventurers' Guild buildings are far from musty taverns. It would be more apt to compare the insides to five-star hotels. The establishments are always big.

Ranks
An adventurer's rank is determined on their ability to defeat magic beasts with the same threat level as theirs if they are in a party, or one threat level below that they can single-handedly defeat. For example, D-rank adventurers can team up with up to five other D-rank adventurers to defeat a D-ranked monster, or they can defeat an E-ranked threat monster by themselves.
 * G-Rank: Newbie with a provisional license. Not an actual adventurer.
 * F-Rank: Apprentice. Beginner adventurer.
 * E-Rank: Average adventurer who can proclaim themselves as such.
 * D-Rank: Mid-rank. Can be a party leader.
 * C-Rank: Veteran. Superhuman by civilian standards.
 * B-Rank: Top class. Usually the strongest member of a small guild.
 * A-Rank: Hero. Select few within a given country. Bards begin singing songs about you at this rank.
 * S-Rank: Legend. Only eight have ever existed. Kings bow before them, and they have the authority to command Guildmasters.

Achieving B-rank and above not only requires combat power, but a track record with multiple achievements and suitable etiquette around nobles. Achieving A-rank requires four conditions to be met: the first is strength, the second is having significant accomplishments, the third is for the person to have done enough for the guild, and the fourth is to be acknowledged by at least 15 different guildmasters.

Services
There are plenty of services existing for adventurers. You can enter the guild's library of information, sell monster materials, take on quests with rewards, and more. Every location has differing services, but in all locations you can take quests, register as an adventurer, sell your monster materials, and other basic things.

Alessa

 * Prevents youth from entering the guild by facing them with Donadrond. The Guild Master is Klimt. One of the receptionists is Nell. Their ace is A-ranked adventurer Amanda. The Adventurer's Guild in Alessa also acts as the Granzell Kingdom's barrier against the Raydoss Kingdom.

Ulmutt

 * Has an alchemist service. The Guild Master is Diaz. Their ace is B-ranked adventurer Elsa.

Bulbola

 * Their Guild Master is Gammod.

Membership
To obtain an Adventurer's Card, a placement test is required. Although there are no age restrictions, some guilds try to prevent hopefuls from entering too young by matching them with a powerful examiner. During the test, the guild is not responsible for any damages suffered.

Trivia

 * In the English Light Novel volume 1, the Adventurers' Guild is referred to as the Adventurer's Guild. This is rectified in later volumes.
 * Adventurers have a tradition: if they feel that a quest is their last quest, they give their cards to someone who will deliver them to the Guild.
 * Adventurers can wear cards of their deceased relatives or friends as talismans.
 * The Sinister Trio are the most hated and unpopular mercenaries within the Guild. They were easily defeated by Fran. Nell forced to them to give her 100,000 gold for the damage they've caused otherwise they will not be healed.
