The Book of Destiny is a powerful demi divine artifact, its core being the Book of the Future, crafted from the remains of the God of Destiny and various rare materials.
Sagus Ancient City is the only relatively intact relic of the Second Epoch discovered by Trolian.
Trolian has organized numerous expeditions to explore it, paying a high price but reaping vast rewards.
During one of the explorations, a High Rank combatant in the team turned out to be a longtime undercover Doomsday believer. Upon returning to the Royal City, he stole the Book of Destiny they had painstakingly obtained from the depths of Sagus City and delivered it to Asa, the Great Sect Leader of the Polluter Sect.
Since then, Asa has been using the Book of Destiny to cause chaos in the Royal City, inflicting great damage on Trolian.
Until Rod found his lair deep in the sewers and destroyed it, recovering this book.
