During World War II, my great-granddad, George Arthur Roberts, was awarded for his bravery fighting fires night after night.

Thanks to him and his fellow volunteers, there was a city to wake up to.

legends about supernatural creatures with the ability to deceive, hunt, and kill humans.

In Slavic mythology they speak about a shape-shifting woodland spirit known as the

Leshi, which is believed to protect the forest from interlopers.

Scottish, Icelandic, and Irish mythology all have stories of the Selke.

A seductive sea creature that starts out in the shape of a seal,

but can shed that skin to reveal a beautiful and a luring human form, which allows them to entice

unwary men to drown in the sea.

Other Celtic mythology speaks of an impish-shifting creature known as a puka, capable of transforming itself

into all sorts of dark animals, such as a goat, horse, or dog. Then of course there's no more famous a shape-shifting monster anywhere around the world

than the Likenthrope, aka the Werewolf, which can be traced back through European legends of the 1500s, and from there back even further to stories from the ancient Greeks.

But throughout the American Southwest, there's a legend about one particular shape-shifting creature that many Native American tribes say is the most fearsome and terrifying of all.

The Navajo have multiple words for the creature, most notably the Yee Naud Lushi, which roughly translates to, by means of it, it goes on all fours.

In English that same creature has been granted another even more descriptive name, the

Skin Walker.

It wasn't just the Navajo either who feared the skin Walker.
