So you want to explore the Sky Platform? Well, keep in mind that your character has to have some form of flight, whether that is teleportation or an animal does not matter. As long as they can travel through the air or across distances without needing their feet on the ground, they can explore the Sky Platform. Remember, you must fill out a request form if you wish to explore the areas in the Unexplored Regions. Once you have filled out that form, post it below for acceptance so that you can start exploring.
Good luck.
