The moment Estraeah's outstretched hand brushes the crystal, a pulse of energy reverberates through her body. Her body becomes lighter, and she involuntarily rises up onto the balls of her feet. She feels as though she might float up off of her feet at any moment. When her eyes flit over, she sees that Klaus has also went for one of the purple crystals.
The last thing she feels before losing consciousness is a gust of wind, inexplicably flowing though the cavern and ruffling her clothes. She does not feel herself hit the ground.
