lavenderdreamz's Hibernal Den

Far before any of the modern dragons, or even their breeds existed, all of the ancients set the grounds for things becoming how they are now. Right before the modern dragons arrived, a big explosion of magic energy (which no one knows the cause of) turned most of the ancients into stone. It's also unexplained why some didn't fall ill to it; those still awake try to protect the ones of stone.
