I'm re-introducing the three original princesses of Equestria! In the Echoverse (AU), Luna and Celestia are still very much involved once Twilight takes over, but they're more akin to royal advisors! Cadence is still the leader of the Crystal Empire too, with her daughter being next in line!

Art and Redesigns by me, lofi-demon.
