Four Portals

You are sitting on a stone. the sun is setting and you are relaxing after a long walk all day. You watch the tribe's children play and you smile at the idea of a new generation living on. You see the sky is an odd purple. This had been happening a few days but tonight you really notice the purple hues of the sky.

FLASH!

You hear a scream from far off. You pick up your sword and run int he direction of the scream. When you arrive you find a woman, not one you know being attacked by animals you have never seen before.
