Dearest Prospero,
Quite some time has passed since this humble servant hath crossed your path. Vast distance hath kept us apart but, I dare say, never far from each other's thoughts. I write, my compatriot, to tell you of my affliction. I find myself seized by fits of distemper, and my nights are visited by vile cold sweats. I have figured it out though. I must have needs meet carried self someplace where I was exposed. I was bitten by that most despicable of bugs...the amour chitin. Dear brother, and close confidant, I need your counsel. I must not succumb to this malaise. I feel I can detect the amusement within you as you peruse my words. If, memory serves...I recall a time when you were afflicted thus...
