It has been over 15 years since the last human sailed the ocean surface of the planet Earth by choice. The Leviathan put paid to the idea of farming the sea.
The Leviathan are a pod of 300 foot long Vampire squid, jet black, inky death that would make a meal of any good sized saurian.
The Leviathan are the end result of 50 years of speedy and somewhat unfortunate evolutionary leaps forward that some of the more morose people left on Earth as “the big step backwards” strange predatory species popped up overnight, meat eating deer, smart and community-oriented apes that used tools and wore clothes, social conservative weasels that walked like men and got into politics. It took scientists 5 years to even notice the weasels. Then there were the millennial squirrels.
Imagine a sabre-toothed, lion sized squirrel.
Got that in your head?
A squirrel that would give your dog good reason to hang up it’s collar and go out to stud for good.
They appeared in the dark forests of Europe and after a few years of culling attempts the European union just evacuated every forest bearing country until the euro-zone was just a bit on the coasts and France. France held out against the squirrels. Turned them into écureuil hachées, what you’d call squirrel burger. They ate horses too, the french.
Now they eat Seagulls. go figure, even the French had to adapt to fishing for birds.
