Ancient warriors are warriors who harness the powers of the ancients. Their power is dependent on variables such as age of the Warrior's race, age of the planet they are on, and age of the universe itself, among other variables.
The use of magic which depended on time and age was first practiced by Aefians about 300 Aefian years (600 human) before Goldas Arenian came to power. It began being used by a select group of people about 10 Aefian years later, who became known as AW, or Ancient Warriors. These people began deep research into Time's effect on magic, and began harnessing use of "Artifacts", which were objects which Mana was building up over time in great numbers.
