Sign your guild charter
When you decide to start a Aion guild, the first thing that you will need to do is to have at least 10 Cronous gold on your tons. Then, you need to head to the nearest large city, such as Undercity (Horde) or Ironforge (Alliance). In the larger cities such as these, there will be a guild area where you can start a guild, design a tabard, and purchase guild tabards.
First, you will purchase a charter f Aion one of the NPCs in the guild creation area of the city. That NPC will ask you to choose a guild name as well as pay your 10 gold to start a guild. Then, you will need to find 10 players who are willing to sign your guild charter. Sometimes this is an easy task, and other times it can take you a week or more to gain the signatures that you need. Once you have the 10 signatures, you will take the charter back to the NPC who gave it to you and turn it in. You then have an active, working guild.
After your guild is active, you will need to organize your guild however you see fit. There are many different ranks that you can add to the guild information, and you can rename them however you want. You will also need to enter in guild information, such as what level RP your guild is or rules that your PvP guild has. It takes a bit to organize your guild ranking and information to the way you want it and it will also change as your guild progresses in size and age.
