It was as I ducked into another building to find another lightless path to continue my escape, that I stumbled and nearly fell due to another wave of pressure hitting me with full force. I immediately recognized it as the pressure caused by the alien sun. And no sooner did I make this connection, than I heard the loud blaring of a horn in the distance: a deep, terrifying sound I am certain has never been made by any instrument before. Certainly in character for that alien.
