"No one really knows what happens to dragons at the end of their natural lives," Sulannus reflects. "They outlive empires, entire civilizations, unless killed. I read a treatise by a sage who had studied the eldest of wyrms in history, who believed that dragons that live thousands of years don't die even then. Rather, they become so large, and sleep for so long...that they simply start to grow into the earth. The dirt washes in around them, and they become mountain peaks, or towering hills...sleeping the centuries away, beneath rivers and forests and perhaps even towns and cities."
