Road to Hades!
It is called 'Styx' in Greek mythology.
In Greek mythology, when Achilles was a baby,
it was foretold that he would die young.
To prevent his death,
his mother Thetis took Achilles to the River Styx,
which was supposed to offer powers of invulnerability,
and dipped his body into the water.
But as Thetis held Achilles by the heel, his heel
was not washed over by the water of the magical river.

Achilles grew up to be a man of war
who survived many great battles.
But one day, a poisonous arrow shot at
him was lodged in his heel, killing him shortly after.
It is said that dipping in the River Styx would give you
an eternal life.
