The Three Sages

Wisdom, Courage, and Power. The three sides of the legendary Triforce, granting ultimate power to whomever wields it. The Triforce was created by the goddess Althaea to test the strength of men. However, the Triforce ending up causing insanity for all humans, and so the goddess decided to split the Triforce into three parts and inject the traits of wisdom, courage, and power into three worthy humans. However, there are still those out there who will stop at nothing to seize the girls who have been injected with the powers of the Triforce and to extract those powers for themselves.
(Probably the nerdiest thing I will ever write. Based off of Legend of Zelda. Don't judge me.)
