In a bleak part of the desert the Mumia stopped. In front of them was a small group of rocks sticking out of the sand. One of the rocks had the eye of Re painted on it. They move past we see the other rocks are actually the pillars with images of the gods chiseled on them.
Deacon: We're here.
In front of Deacon you see a small dune of sand, but this dune is different from all the others, this dune is made of darker sand. This dune is wet.
Mohamed: And Re brought the heavens down on the temple.
They dismount and move towards the dune, Lara being pushed the whole way. We see the dune; there are no doors or keyholes of any sort in the sand. Deacon walks over to Lara and digs threw her backpack until he finds another plastic explosive. He takes the small bundle of dynamite and places it on the dune. They all step back behind another group of dunes just to the left of the explosive. A small bleep followed by a BOOM indicates that the explosive did its job. They turn to see the dune is gone and all that is left is a stairway going down, into the earth.
