A mysterious green haze filled the sky over Alltree Island, and it brought fear to those that lived in Evergreen Castle. Over the years, many a witch looked up at the green haze in the sky. However, only one witch knew what caused it, for she saw the Horse Dragon come through the portal spewing green flames from its nostrils, carrying a traveler. The Horse Dragon offered her a warning. "Be mindful of the travelers for some carry evil in their hearts." Now, the Horse Dragon has returned and brought a new traveler to Alltree. The people of Evergreen are right to fear the haze, for this traveler comes seeking revenge. Will revenge be enough to quiet the pain within this traveler's heart, or will it only worsen it?
