Mysterious chronicle (part 2) is a book found only in Daemonheim. It may appear in front of the dungeon-ending ladder after killing the boss monster.
It was written in the year 1241 of the Fourth Age and is Bilrach's second entry. He explains about how after years of searching and evading detection, his research led him to that castle. He draws similarities from it with the Dragonkin and queries why they would leave such a place.
Year 1241 of the 4th Age:
After years of evading detection, my research finally led me to the castle above. It seems similar to that of the Dragonkin of old: protectors of the artefact, enders of the Great Wars. Of course, I should have suspected It to be hidden in a manner as straightforward as this! fools to abandon such a place; why would they move on? It must all be linked in somehow, but time does not allow for further investigation. My power now is to be used on one thing: forging through the very earth that separated me from my goal.Praise be to Zamorak!
