" They "

The ship made its way through the thick fog.
It was quiet. Deathly so.
Absolutely nothing could be heard beside lapping of the waves and the occasional rustling of clothes.
The atmosphere between the sailors was tense, they shushed each other from time to time when someone accidently moved.
They were tense beacuse they knew.
The fog wasn’t natural. Until an hour ago the weather had been beautiful.
So they knew there was something wating, watching them...
The Captain of the ship stood at the helm, cutting a lonely figure against the dim light.
He watched too.
He watched the sea for any tiny movement that wasn’t calm waves and for Their shadows in the water.
Because They were there.
And They were hungry.

This was actually supposed to be the start of a short story but at the moment it's stuck in mini prolouge form.
