What are They?

The figures moved toward me slowly. They were all black with black eyes. When they came a bit closer I saw that they had a red shine to there eyes. Just then one of raised his hand in the air and the next thing I knew the sky turned from red to black. Then they just walked away as if I was not even a threat. I became confused. The black figures walked back into the building. I quickly followed them in hope to get out of the desert of ash.
