You know that orb in the sky who light the day? It’s the sun. It goes by many names… Apollo’s Lantern, Day Moon…
Its light takes 8 minute to reach the Earth. This means that if the sun disappeared, we’d only know about it 8 minutes after the event, and that would be too late to find out who took the sun.
But we’re only a level 5 planet. Those things should be left to those who can do something about it, like the Doctor or the Shadow Proclamation.
