This Valentine’s Day, my lovely girlfriend received this handwritten note, along with an elaborately crafted key. The contents of the mysterious letter are included, transcribed here:
I hope that this letter finds you well. It is a matter of some importance that I illuminate for you some of the unusual happenings throughout this otherwise peaceful town. Recently, as the nights have grown longer, a series of strange events have begun to plague our beautiful city. As you know, not only do our friends not seem to see the shadows lurking, but indeed they even seem to welcome them! Imagine! What moxy. But certainly, I digress. Each of these events has come in triplets. Three of three. I don’t need to tell you of the importance of such a coincidence. It would surely seem unremarkable to an untrained eye, but I suspect that you understand. A woman of unique vision in these matters!
With that, I entrust to you this key. If all goes to prophecy, there will without question be a moment of unrelenting horror lurking above the peoples of this and nearby counties, and in the future, as seemingly distant as our interstellar neighbors, a door must be opened. It seems that at long last I have uncovered the key for just that door! Keep this near to your heart; a strange and bitter darkness moves between the stars. Restless. Eager.
It is dangerous to go alone. Take this key.
The key. What door does it unlock? What horror is it hiding? Where will this strange adventure take us?
