Dragons of Atlantis just released the 4th outpost, the Wind Dragon Outpost. To create a Wind Dragon Outpost, you must own a Fire Dragon Outpost and find a Wind Dragon Egg. To find a Wind Dragon Egg, you must attack level 7 or higher Savannah wildernesses. I will be putting out a guide to farming for your Wind Dragon Egg shortly and also a guide to setting up your Wind Dragon Outpost. Good luck!
