Entry for the 24HoSMW #13

Name: Aurora Hills
Exits: 1

Explanation: (From Wikipedia) "An aurora, sometimes referred to as polar lights (aurora polaris), northern lights (aurora borealis), or southern lights (aurora australis), is a natural light display in the Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic)."
In this entry, the aurora is made with green gradient. It could have been done with custom GFX, but there wasn't time for it.
