Instructions
Purchase the "Mabinogi" Premium Service Package if you don't already have it.
Go to Dunbarton in the east of the Uladh kingdom and buy a Guild Deed for 1,000 gold from Eavan in the Town Office.
Collect together four other "Mabinogi" players in your party who are not currently in a guild to join yours. Set the guild leader as the leader of the party.
Use the Guild Deed item and choose a name and type for your Guild, and have the other Guild members approve these choices. The Guild Deed will turn into a Guild Stone.
Go out into the countryside and find an open spot in a field to place your Guild Stone. Place the Guild Stone on the ground and your Guild will be confirmed.
