The Great Families were feared– reverenced for many things, but three of which stood out to the others the most.
The first was their deep-rooted history, the tales of the 12 Heroes and the goddess Mayura. How she had come to the world bearing the gift of the System for the common people when twelve ordinary humans had surpassed their humanity and attained something else. The use of energy as a fuel for their abilities was merely a compliment to the array of skills they had learnt at the time.
It was because of this that they stood out through history, prolonged their bloodline and thus became the twelve most powerful families in the kingdom.
The second was their skills. Their sword arts, weapon Mastery, and magic spells. Passed down through lines of descendants. Stretched. Warn out and Upgraded every few centuries.
The nature of their skills came about after constant use and disuse. A matter of evolution that fostered their techniques into the world– a shattering phenomenon.
