Once Karthus was born in his lair, he used his blood moon to summon burdenates to destroy buildings in the pit, but the lumicons saw them and started fighting. They eventually got to use the Fortress after several mansions got destroyed. Over the years, Karthus eventually was able to summon the first two Karthium Bosses Pumpgrim Reaper and Demonishife, and they destroyed the fortress about 500 years later.
