Hans jumped from one little glacier to another, quickly passing by tens of them, before reaching a bigger one, on which he stopped a second in order to see if he could spot the shore in any direction.
He watched carefully forward, squinting his eyes, but the only thing he could see was the lake and the little islands,
"Blup"
Hans turned around as fast as he could to identify the source of the sound.
Where it came from, the surface of the water had just broken, and ripples had formed.
When the ripples disappeared, and Hans came to the conclusion that it had been just a piece of ice falling off a nearby glacier, the sound was heard once again.
"Blup"
Hans turned to his left this time, as fast as he could, but once again… nothing.
At that point, he could tell something was off, something was extremely off.
