Destiny of Ancient Kingdoms (DOAK) currently offers you three different Kingdoms for you to explore and conquer, they are called:
The Kingdom of Dragon
The Kingdom of Magic
The Kingdom of Nature
None of the Kingdoms trust each other. Sometimes they help each other to gain trust, other times they betray one-another in an attempt to conquer each other's Kingdoms.
Every Kingdom has a map called the Ancient Battleground which is located on the border of each Kingdom.
Players can enter an enemy Kingdom by teleporting through a teleporter from the Ancient Battleground.
Most of the conflict between Kingdoms is due to player vs. player activity and most of it takes place in the Ancient Battleground.
You are able to select the Kingdom that you want to join while you create a character.
Please note: You have to make sure you have selected the same Kingdom as your friends if you want to form teams with your friends.
Otherwise you will be each other's enemies because you are from different Kingdoms.
However, if you are tired of your Kingdom then you can change your nationality in the game after level 35.
