Mysterious chronicle (part 2)

''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 separates me from my goal. Praise be to Zamorak!
