In the kingdom of Noarth, there was a king who had twelve beautiful daughters of various ages from various women throughout his years.
They slept in twelve beds all in one room a when they went to bed, the doors were shut and locked up tight, for there was fear of hidden attacks coming from the warring kingdom of Bra'Ah.
But every morning their shoes were found to be quite worn through as if they had been dancing in them all night. And this continued for three nights, every month and yet nobody could find out how it happened, or where they had been.
And those who tried to find out...
Paid with their lives.
