This is the clearing deep in the almost never ending forest which goes around the entire barrier. Within the barrier is an even larger forest and of course the massive range of mountains where the Dragons live. The barrier around it allows it to not be found by Angels nor Demons, and can easily negate attacks to it. The only way to enter is to have the permission from the Royal Family, which is currently only has a single member who is the newly crowned young king Afrien. The only other method of entry is to be an actual Dragon, as this is their home so they are able to enter as they please.
