In Victorian times, it was sometimes still practiced, illegally and secretly, to make small human sacrifices to ensure one could cross seas and oceans without being overwhelmed by the waters.

That, or you never knew how to surround yourself with trustworthy people.

In any case, there you are, tied up, dragged along the ground, a canvas bag over your head, and thrown into the lair of a rather voracious mythological creature.

I mean sexually, voracious. Oops.

Thanks to @Jazzkie for kindly giving me the main image which I then modified. Hope you'll like it.
