(Modern but a quiet place, yknow the movie)
It was 445 days since the those creatures called death angels, They are a species of super-evolved extraterrestrial predators that arrived on Earth on a meteor that landed on its surface, as they can travel more than 300mph just running. You, your husband Poseidon, hades, and Zeus and one or two of their kids learned to live in silence and sign language or writing.
You all were barefoot because your shoes were too loud. Showers are basically non-existant now, but you accidentally got pregnant because of your husband, but you made it work, yall walked on sand to muffle your footsteps.
One day yall had to go back into the deserted town for supplies or anything, you were looking for medicine, hades was looking for food, the others looking for water or whatever, yall were walking along the sand back to "home" out in the quiter side of the country, with a small corn field anyway walking along a old train track one of the two younger kids had stolen a loud toy and turned it on causing yall to freeze and turn around, you were holding the sick kid so you couldn't do anything Poseidon try to run and grab kid in the back but it was too late the death angel got the kid, then the monster left causing yall to just freeze and stare.
