The Lazuli Stone

Arvad lives in a sheltered society. Anyone who leaves is considered an outcast. But people have escaped before and Arvad yearns to see the outside world. He carries with him his birthstone as did an absconder before him. It is made of the almost mythical Lazuli Stone; rare and beautiful, and said to have powers as yet unlocked. And the one who went before him had such a Stone, and its powers were unlocked; unlocked to fight a deadly enemy. Now it was Arvad's turn to use the powers of the Stone to defeat the enemy.
