Training Session
We all knew Twilight Sparkle was a powerful sorceress, but none of us had ever realised just how powerful she truly was. It is no underestimation if somepony said that she’d be able to challenge an immortal to a battle and come out as the victor. The possibility was there, of that there was no doubt, the only thing that was needed for her to actually defeat an immortal, such as myself, was for her to realise her full potential, for her to realise just how much power was stored in that small body of hers
Power is no good if not controlled. A training session between Twilight and Luna escalates into something it should not have.
Those that go mad needs to be put down. Twilight learns this, even as she tries to reason.
