Magic

Magic is a life used to create and, in some cases, destroy. Only the Eddonians have a powerful enough connection to nature to harness it's power for magic and even then they only uses it for rituals and taking care of the land or their villages. The Imalti seek to learn how to harness these powers and use magic to create an army no nation could withstand. You'll have to learn how to use magic if you want to save Eddonia and stop the empire.
