This piece is hugely inspired by The Twilight Zone, and also The Scary Door, from Futurama. A rather literal take on Alien Invasion, but one that's hopefully enjoyable nonetheless.
Until a few hours ago, this was a quarter-done and I wasn't intending on entering this round of the contest. It's current 2AM local time, and I've got to be up for work in 5 hours, but I'm glad I got this written and posted. Huge thank you to Pedagon for their, as always, immensely helpful critique and proof reading.
