Welcome to the Quest… (so it begins)

My name is Adam Guthman. On July 4, 2012 I found a box awaiting me in the vestibule of my apartment building. Affixed to this box was an envelope on which someone had written “Remember?”. Inside the envelope was a generic Christmas card over the front of which “1(6|9)” had been scrawled with black marker. The interior of the card read as follows:

Greetings Mr. Aba,

The box on which this card arrived contains The Great Whatsit, a deus ex machina of sorts, a device capable of delivering unto humankind that which it has always sought at the time that it is most needed: Salvation.

Only you, Mr. Aba (aka Adam Guthman), may open this box to find the contents therein as described. However, you will only find them therein if when you open the box you can correctly answer the following question: Who am I? (As pertains to you, not I, smart guy.)

Understand that there is a deadline; the box must be opened by December 20, 2012, 11:59pm EST — just one minute before the 21st, the date said to mark the end of a 5,125-year cycle in the Mesoamerican Long Count Calendar, i.e. the end of the world.

As I’ve consigned you to play detective, I offer this clue: Start in the middle and then go back to the start. From there proceed to the end. If you pass the beginning again you’ve gone too far, dear friend. (And, if with that you still feel thrown to the wolves, I’d suggest starting with them.)

Best of luck,

G Sleuth

It’s a mystery it seems, a question of identity, and I’ve only got so much time to solve it. If you think you can be of some assistance, start In the Middle or Otherwise.
