Shrieks could be heard as strange creatures ran one way and another, many looked up at the sky, fear in their eyes, they knew what came their way.

The planet crumbled until it was nothing but shattered pieces of rock. Many of the rocks started drifting away from the mess and away.
Thousands of years later five pieces that ones were part of a planet were pulled into earth's atmosphere. One lands in Arizona breaking into some caves. Another lands in the Mountains of Santa Cruz, the last meteor seen lands in Texas away from civilization.

One lands not far from a live Volcano, while the other lands not far from an army of strange and ugly creatures. They back away from the rock and the heat that comes from it.
Meanwhile somewhere else…
