Secret of Babylon - Basic information

About 3500 years ago, the Lux Veritatis was the most powerful order in the ancient Babylon. Its priests controlled the city and protected its inhabitants from the dark powers. The most dangerous object that they have protected was the Book of Death, which could be used for summonning the demon of the underground. But suddenly, a traitor has appeared in the Order. His daughter Kraene knows about his plan and has to make a very difficult decision...to help her father doom the world, or to venture her own life?
