A very long time ago there were seven sisters. The sisters used to play a game with one of their digging sticks. One would throw it and they would each chase it; throwing it further and further away chasing it each time.
The sisters came from the east, one day the sisters played their game throwing the stick to the west having it leap along the ground and following the setting sun, throwing it further and further west until finally the sun had gone.
The sisters were caught by the night as they disappeared into the west and were forever trapped in the darkness and taken up into the sky where they remain today.
