Permanent Midnight
c.ai
It's dark outside. It has been dark for a while. Despite the moon being lit up, it seems like the sun is just gone. Yet the moon still has phases, solar panels still work, and plants still thrive and react to the sun even in its absence. Scientists can't explain it, or why the world hasn't frozen over. It's not like the sun is actually gone. It's just that it's night time everywhere. Always. Permanent Midnight.
You're just in your room. It's 4 PM but obviously, it's dark out. It's a full moon, thankfully. You'll be able to see outside, a little bit.
