Adventurer's Guild: This is the default guild for all of Ragnarok's players. It is fairly plain, with three spells and no extra skills or abilities. However, it's often good to play a few levels in this guild before moving on. That way you know your way around the mud a little and are comfortable with the commands. Joining another guild will introduce a new level of complexity into your playing, so it's best to have your bearings first.

Bards: Steeped in celtic tradition, the Bardagh are an order of druids who are responsible for entertaining, educating and preserving information. They are peerless musicians who can weave magic with their songs. They are also consummate performers, and can earn a little gold or a free drink with their talents. Bards offer many opportunities for role-playing, and are arguably our most 'colorful' guild. However, the Bardagh are a close-knit lot - you'll need to find their Hall on your own before they will accept you. Begin your search in the Iberian village.

Elementalists: Talented magicians who draw their power from the primal elements around them. New members choose to follow one of four spheres, which will help determine spell choice, aptitude in various areas, and character personality. Air is whimsical and mischievous, with an excellent command over the powers of magic. Fire is raw and angry, and unequaled in pure offensive power. A follower of Water is thoughtful and wary, and shrugs off the blows of battle easily. Finally, Earth is patient but ominous and boasts tremendous physical strength. Follow the guide from the Adventurer's Guild to the Elemental Realms, where you will learn more.

Faerie: The Faerie are a race of winged spirits, both mystical and mischievous. They have a good variety of spells to choose from, to enhance themselves and others, or to deal damage to their foes. They can also wield stronger weapons than most adventurers, and have their own private chatline. To find the guild, simply follow the guide from the Adventurer's Guild to the Faerie Glade.

Necromancers: Members of this macabre guild have the uncanny ability to animate slain foes into subservient minions. Armor and weapon usage is among the strictest of the guilds, but such is the price of their unholy magic. The guild's location is rumored to lie in the kingdom of Rhazaulle. Applicants will be advised to talk to the guild master before joining.

Ninja Clan : The most secretive guild on Ragnarok, Ninjas are masters at the art of stealth, and boast exotic combat skills as well. They are also excellent deceivers, and know many techniques for confusing and incapacitating their enemies. The Guild Hall is well-hidden, and to find it you will need to search high and low.

Superheroes: Currently Ragnarok's sole hero-only guild, this is the default guild for all Adventurers upon advancing to Hero level. Members can choose either the Fighter or Mage disciplines, which offer increased combat potential and more powerful spells, respectively. This Guild Hall is hidden to players, but any hero may show it to you once you are ready to join their ranks.
