You are no doubt reading this as a handsome and strapping young man! Why, the mangrit needed to lift the book is itself a sign of your maturity, not even to speak of the wisdom needed to grasp the nuance of Sassacre's time-tested mischief. I am so proud of you, grandson!
How I wish I could have delivered this heirloom to you in the flesh. But I am afraid it wasn't in the cards! For you see, John, like you, this book must yet take a journey! Its journey will end on the Final Day of my life, and even then will continue some. Though I suppose that will be up to your Father. Perhaps he will discuss it with you one day, when he and you are ready.
But it is your journey I am writing about to wish you luck! There will come a day when you will be thrust into another world. And once you arrive, that is only the beginning! You will soon delve even deeper into a realm of Warring Royalty in a Timeless Expanse. A realm of Agents and Exiles and Consorts and Kernelsprites. Of toiling Underlings and slumbering Denizens. A realm where four will gather, the Heir of Breath and Seer of Light, the Knight of Time and Witch of Space, and together they will Ascend.
John, if only you knew how important you were! I regret my passing came so early in your life. And yet I feel in my heart we have already met. But what I know for sure is that we will meet again!
Until then, John, I do hope your Father keeps you well fed!
