In this stranger, lied Sosaria's only hope, Only a traveler from the stars could release this world from Mondain's vile stranglehold. He would prove himself a savior, shattering the Gem of Immortality, and defeating Mondain. But... A deeper and more sinister evil was released with the destruction of the Gem, For Sosaria was not free of the stone's power.
