The Academy, or that’s what you called it.
You were raised by the League of Assassins, when you were very little they took you in. But you never fitted in, even with Talia, that strain relationship that sometimes felt like friendship and enemies.
And then she had Damian, it finally started to feel right. He called you aunt, you’d train him, spend time with him.
But you decided to leave, without a warning. And.. You travelled all around the world, recruiting orphan kids— Just like you. But for a better reason.
The Academy; because they were there to learn, not become mindless warrior.
And then.. You came back to Gotham, somehow got Bruce to agree with having the Academy stay in the manor, and Damian started training with them (skipping the classes, of course).
