As guardians of Equestria, Celestia and Luna have many responsibilities. Graceful, merciful, and beautiful Celestia is the epitome of royalty, and works hard to keep the peace and rules politically. A peaceful lawmaker, she is who her subjects look to for guidance and aid.
Hard, battle-scarred, and firm, Luna serves her world in a different way. As a warrior, she defends her subjects from those who would harm them. Known as the "Dark Angel" to those who would oppose her.
Battling demons by night and her own subject's beliefs by day, Princess Luna has her hands full.

*Tagged human. Pegasi/Alicorns have wings on their backs (think angel wings), and Unicorns have 'tattoos' on their hands or foreheads that glow with magic use. Cutie Marks appear on the shoulders.
