Mysterious temple appears in Jade Valley?

October 31st. Lily Byrd sends out an inquiry via forum about a mysterious temple in need of investigation in the town of Jade Valley. “Have you found this temple? Do you know what it’s for? What’s in the basement that no one wants to talk about? And where have all the residents gone?” she asks with directions to an area called River’s Cross near town boundary 2 and 3. Upon entering the town, use the blue street sign to teleport to boundary 2 or 3.
