The tutorial will bring you to the Hall of Nations in New Nauru, where you can view all the Player Nations currently active on Atlas. Right-click the pedestal display beneath a Nation’s banner to read the information posted by its leaders.
To request to join a Nation, simply click on the Request Invite button on their display. Alternatively, you can reach out to a Nation’s leaders directly to request an invite.
After completing the tutorial, speak to Captain Horatio at the Hall of Nations to found your very own Nation - all that’s required is a name!
A Nation itself does not provide any land - but a Nation can found up to 5 Towns on the continent of Athera. Towns are land-claims that can be expanded, leveled up, and even fought over.
Founding a Nation will grant you a free Town Hall Spawner. This item can be used to claim your very first Town on Athera! Simply travel to an unclaimed area of wilderness, and right-click with the Town Hall Spawner on the spot you want to found your Town.
