There is, I know for a fact, a special drum in the Blizzard offices. This drum is chained in a dark oubliette “lest it awake”. Carved from glimmering red-flecked obsidian, its five-metre span is topped with a skin that feels eerily familiar. Some swear they’ve seen obscene glyphs tattooed into the skin, dark marks which vanished upon blinking. It is Blizzard’s launch trailer drum. Crows rising from the trees this morning to pelt themselves at my window mean the drum has been sounded.
