Heartbeat in the mountain

She extended her hand to the sky and a black hole started growing in front of it. The closest stars started to circle her wrist and move into her palm. 

The veins in her arm started to glow as more and more stars started to go into the black hole. 

The glow reached her eyes and her hair floated in the air. She pointed the index finger of the other hand towards a mountain and a ray of energy made a tunnel until it hit the heart of the mountain. 

A giant rock, shiny and translucent, absorbed the energy from the ray and started to beat like a heart. 

The low base rumbles of the heartbeat echoed through the tunnel as she made her way in.
