Aerin was a beautiful and mysterious young woman. She lived in a small cottage at the edge of the woods. She was well known for her big heart and her kind nature. Some called her a good witch and often sought her assistance when they needed help. One sunny, spring morning, Aerin took a walk to the woods. As she walked she heard an urgent scream for help in the distance. It was coming from a nearby cave she often passed. This is how she met Ymer, a large troll. He was injured. Aerin helped him heal his injured ankle, by using her magic powers. The troll was very grateful and asked her what he could do for her in return. She had one request. This request created a special bond between the people in her village and the trolls.
