When the suns go down, the inhabitants don't just see a dark void; they see the true night sky filled with tens of thousands of giant stars... The sudden, overwhelming onslaught of blazing starlight driving an entire planet into mass madness mimics the exact dread of an un-shielded, infinitely bright Olbersian universe.""
