Creating a guild is really simple, in fact it takes only 100.000 coins to create one. To create a guild you need to go to Talon or Cleo, press on the "GUILD" button, choose a name that you like, and that's basically it, your new guild is born!
After you created the guild you will need other players to join it, to do that u will need to find another guildless player and press on the "GUILD INVITE" button and wait for a response!
As a leader (General) you will be able to kick other players aswell as promote them. In fact, a normal member of your guild won't be able to invite other players to your guild, to do that they will need a promotion (Vice). The last thing you can do is add a description to the guild where you can put just a simple phrase or maybe a link to your guild discord server or whatever you want; to do that you need to press on the "EDIT" button, write your description and in the end press on the "SET" button.
Have fun with your guildmates!
