The moment Estraeah's outstretched hand brushes the crystal, a pulse of energy reverberates through her body. The glow of the crystals grow brighter, making her eyes sting. Her flashlight beam grows steadily stronger until the handle grows hot in her hand, and she has to drop it. When her eyes flit over, she sees that Klaus has also went for one of the white crystals.
The last thing she feels before losing consciousness is a deep thrumming in the air, as if she can now deeply sense the world around her in a way she never could before. She does not feel herself hit the ground.
