you can create one, or join one up. for me a guild is the most important thing in SRO. ive been with the same ppl in a guild for over 3 years and we are great buddies. without guilds SRO will be faaacking boring.
you can make one, or edit yours at the guild manager in every town.
if you wanna join a guild just go ask people if you can join a guild. dont forget to inform about the guild, cuz when you leave, you got a 3 day penalty. also dont join just random shit turk guild
