The sirens, three charming creatures with the ability to turn Equestria to darkness, banished, and forced to disappear forever. Starswirl thought he'd forced them to a place where their magic wouldn't work, yet it seems it's not this way, heck, it's much more easy to manipulate these walking stick figures!

Tossed out on the stone streets of a different kind of Equestria, the Sirens will face their biggest challenge yet: Learning how to be a human.
