You awaken with a startle, the clang of metal against metal resounding in your ears. To your left, someone’s scream of anguish is cut ominously short. To your right, a primal war cry, mixed with the menacing growls of large feral creatures, chills you to the bone. You bolt up from the couch in a panic, only to find that you’re not in danger after all, at least not of being gutted by a Death Knight. However, your gamer spouse, who is stabbing frantically at the keyboard, eyes glued to the battle unfolding on the computer screen, might be missing some vital limbs soon if you don’t both get some sleep.
