Welcome to Fairytail-RP.com, I am Niyol one of the various moderators on this site. I apologize for your previous one declining, and I would like to say that all sites have their ups and down. I personally believe had you stuck around a bit, the site would find some way to bounce back. But their loss has brought us all a new friend, so welcome again, Brother (or sister) Shu Toro.
There's many guilds, and factions you can join up with. The Legal guilds are: Sabertooth, Blue Pegasus, Black Rose, Lamia Scale, Fairy Tail, and Infinity Hydra. If dark guilds are your fancy, we have Savage Skull, Basilisk Fang, and Tartarus. For guilds that are on neither side, you have Laughing Coffin, and Sleeping Forest. There's also 3 faction; Guildless, Rune Knights, and Magic Council.
Below is what the central focus of each guild is.
Lamia Scale is currently trying to rise from the ashes, so I'd personally reccomend joining them IF the character you wish to create enjoys learning.
Blue Pegasus is about being heroic.
Black Rose is a bounty hunter guild.
Infinity Hydra is about stopping dark mages, and protecting Fiore from their influence.
Fairy Tail is centered around friendship, and the bonds they share.
Sabertooth's main focus is being chivalrous, and knightly.
Basilisk Fang wishes to destroy the current world, and rebirth it in an age of anarchy.
Savage Skull is about doing whatever it takes to make bad things happen.
Tartarus is a guild thought to have been wiped out, but are secretly planning their return. Please send a Private Message to the Guild Master (Gil or Voluptuous Venir) if you wish to join.
Sleeping Forest wishes to preserve and maintain the balance of Good and Evil in this world, no matter what it means they have to do.
Laughing Coffin is a mercenary guild, if you ever need a job partner they have a thread in their guild hall where you can request one.
Guildless Faction are mages like me who have no guild, and aren't bound by the rules of being in one. There aren't any major benefits, but it does allow you to choose your destiny.
Rune Knights are like national guard for Fiore. They work directly for the magic council to protect the citizens.
Magic Council is government, and has many mixed opinions about them. Last I checked you needa be A Rank to join. ((All new people start at D Rank))
