Message in a bottle

"David, or should I say Misty, it has come to my worst fears. Undoubtedly you have witnessed the attack of all of our bases on your LAPTOP, and have tried to communicate with SAGES, only to find none left. This is because our fail safes kicked in before the DEVILS stopped it. The reason you are still there, you were registered to the system as David, and so it did not realize you were a SAGE at that time. This is part of our security, it allows us to trick our scanners so our SAGES can patrol. At that moment, there were 10 more like you, SAGES in alternate forms. I am entrusting you with some great responsibilities and powers. You are the last hope."
