Mysterious chronicle (part 4) is a book found only in Daemonheim. It may appear in front of the dungeon-ending ladder after killing the boss monster.
Written in the year 1285 of the Fourth Age, Bilrach craves for more progress. He needs to work on re-awakening his lost power, as while his mighty slumber restored a large amount, he expended most of it searching for the location to dig and evading detection, which required some interesting methods and a lot of disguises. He believes in time he will regain all of his power and break through the world with a fury, as to make Zamorak proud.
Year 1285 of the 4th Age:
There has been acceptable progress since my last entry, but still I crave for more. I will have to work on re-awakening my lost power. While my mighty slumber restored a large amount of power, it was once again lost in my great search for this place. Evading detection required some interesting methods and many disguises, which has again left me drained. I have faith. In time, my full power will return once more and, when it does, I shall break through the world with such a fury as to make Him proud.Praise be to Zamorak!
