A/N: I've had this idea in my head for a little while now, and I want to get it out. Don't expect chapters right away since this is not on my list of priorities right now, but rest assured, I will eventually be writing chapters for this story.
Disclaimer: Harry Potter is owned by J. K. Rowling. The Cthulhu Mythos is based on the work of H. P. Lovecraft.
It has been many long years since the day it all started; I was younger then, quite a different person than I am now. Other memories have faded, but this one remains as sharp as when it occurred, even to this day. I must confess that it never occurred to me until recently to share my experiences, and I sincerely regret not doing it sooner; a good number of people would have been much better off had I done so.
I am writing this because it must be known. Though it will not do well to unleash this knowledge upon an unsuspecting populace, you who take up the torch or who have been forced into it, should at least be aware of the dangers you face and the horrors you will encounter. I have included as much detail as I can remember, and as much information as I believe is necessary to give you a fighting chance. I fear though that time and terror may have caused errors to creep into this writing. Certain events may or may not have transpired, people mentioned may be real or figments of my imagination - but I have done my best to check with the others on their veracity. Included are sketches and notes regarding various cults, chants, artefacts, and other things encountered during this time.
You may scoff, you may laugh, or even deny. However, once you have experienced what truly lies out there, that which stands right by the door - you have been forever tainted by their presence. Your past but a dream, your present a nightmare, and your future that of madness. Do your best to keep whatever tenuous grip you have on your sanity, for it is all that stands between you and the loss of your identity to some alien design.
Yet, that is not to say there is nothing that you can do. For though you cannot destroy them, you can delay them, perhaps indefinitely. Or perhaps not. As long as you are willing, there is a chance, and all is not lost. We are few in number, but we have persevered, and thus stayed their hand so far.
Rather then flail blindly in the dark like I did, you have a chance to do better. Do not hesitate to share this with those who will benefit from it, but be careful of whom you might be sharing it with. There are those out there who search for that which man was not meant to know.
Dear reader: you, who hold this book in your hands, can never return to your blissful ignorance.
Sincerely yours,
Harry James Potter
