How was Devil's Tower formed? Why do some people get struck by lightning multiple times? While some may write these off as random occurrences, might they instead point to a new understanding of not only our planet's past but also its future?

Abandoned cities. Ancient cultures nearly erased by time. And colossal empires that simply vanished without a trace. How does a civilization become lost? And what could cause once-thriving groups of people to just abandon their great cities?
