The Jewels of the Ishamah

Long ago, in ancient Mesopotamia, four jewels were guarded by four clans within a secretive sect collectively calling themselves the Ishamah--jewels of Earth, Water, Sky, and Wind. When joined as one upon an ancient altar within a hidden temple these elemental jewels are rumored to endow great mystical power and possibly even immortality itself upon the one who unites them; unleashing the true essence of their collective power through a magical tablet known as the tablet of destiny--which can bestow godlike power to the one who unites all four jewels, and utters the ancient spell written thereon to usher in a new Sar or age.
But the sages of old who harnessed this great power deemed it too volatile to be wielded by one person for fear that it would fall into the hands of a corrupted madman. This is why the jewels were kept hidden and secret, their unpredictable power guarded and kept separated by the four clans of the Ishamah for thousands of years--each jewel kept hidden by each clan.
Within one of the clans, a young man named Kish-rin is coming of age. As a 20-year-old young man he is expected to tackle the responsibility of becoming a chief guardian over the Mu jewel, the jewel of Water and Life, which his clan guards. Meanwhile, it is discovered that there may be a traitor among them. It is up to the Ishamah to unite in order to unmask this traitor and their mad plot before it's too late.
