After reaching level 12, each player who isn't a member of any guild can create their own guild. To do this, press the Guilds icon at the bottom of the main screen. The Create button is located in the bottom right-hand corner of the window that opens. Pressing this button will open the Create a Guild window.

In this window, you need to enter the guild name and description, then select the guild language and emblem. You can also set the level at which players can join your guild. By choosing the guild type, you determine whether players can join it immediately or only after you accept their request.

Creating a guild costs 15 rubies.
