Challenge

With the passing of a most competitive king, Stronghold is now wondering who is to inherit the land so many witches and faeries inhabit. Only three of king's sons are alive (four dead) Primus, Tertius and Septimus. Of course the king killed all his brothers for his place and is disappointed with his sons' inability to finish each other off; that is until only one brother remains. The king then devises a challenge; he throws the Stonghold Topaz into the air and all the sons watch with amazement as it floats upwards into the sky. "To him who retrieves the stone, which is the Power of Stormhold, I leave my blessing, and the Mastership of Stormhold and all it's dominions" (Gaiman and Vess 59). And then a star falls and the old king whispers, "There," and dies. So, the old king left this great challenge to his sons; some not so bright, to find this Topaz that floated up in the sky.
But, what if the star falling has something to do with the Topaz? What if they are related in some way? None of the sons have any idea what do to so a great challenge this is.
