Twilight’s horn starts glowing magenta, followed shortly by Celestia’s glowing yellow and Luna’s blue. After hearing the quiet thunk of the generator’s contacts engaging, you can feel Twilight’s breathing quicken, and become more labored, under your arm. Her wing feels like it spasms around your shoulders, and you bring up your other hand to close around the end of the limb, to steady it, but she makes not a sound.
