The mysterious box disappears, replaced with a letter

[Leadmau5]

*As Lead walks down the same road the next day, he notices the box is gone, but it is replaced by a letter? He picks up the letter, confused and starts reading it.*
"Con..." Lead laughs, as he talks to himself. "What kind of name is that? What kind of crap is this?"
*As he reads on, he slowly becomes even more confused.*
"Rules.. blah blah.. Stop the evils? Bring peace instead of war? 'Con, the All-seeing Eye'?"
Lead mumbles to himself at how stupid the letter sounds.
*As he turns around to walk away he notices the box, sitting on a small stand. Some paper is near the box, on the stand.
He reads the note.

It is now up to you, what will you do? Will you help the cause, or will you ignore the call of Con?

*He approaches it and picks up the feather next to it, lightly dipping it in to the ink, and writes on some of the paper as if hypnotised.*
"I will help the cause of The Watchers."
*He slots it in the box, and walks back home, snapping out of the hypnotism.*
