After accepting the mission Elena left the city and flew toward the north-eastern direction. A few hundred kilometres ahead there was a forest in this direction and that forest was the home to a Forest Dragon.
Forest Dragons were a very important part of a forest. It's not like a forest could not survive without a Forest Dragon, but any forest that was inhabited by a Forest Dragon would be better and more resourceful than other forests with no forest dragon.
The forest where Elena was going was called the Great Forest of Nores. This forest had three large or medium cities around it and all three of these completely depended on the forest for their economy. That was a direct proof of how valuable that forest truly was.
