Due to Onyx's size and serpent form he was able to move much faster through the burned farm lands. He noticed that there were many guard and adventurer patrols along the way and did not hesitate to greet most of them. They more or less recognized him due to the plaque attached to his neck but had trouble understanding how such a small serpent was suddenly bigger. Onyx found it very comical when he needed to explain it all.
After surpassing the farmlands with his speed he was back in the familiar fields outside of the city. However, this was closer to the swamplands that contained dangerous poison type monsters. Onyx was not going to get close to them but he could still see the change in the terrain from where he was. If he was not careful and drew too close he could end up facing something he did not wish to battle against.
