Black Dagon is the second book in the March of Dagon series. It depicts the events of Dagon's March, from first-hand accounts from survivors, soldiers, to the diary scraps found in the ruins of the cities, and from Llervu's personal account as well.
Many years after the end of the Oblivion Crisis, daedric worshipers have enticed an entirely new threat. Combining dark magicka together, they have figured out a way to summon the Daedric Prince of Destruction, Mehrunes Dagon, back into the mortal realm. And with the Empire just recovering from the Crisis, they are less than prepared for this new war. It is only with the hope that the Champion of Cyrodiil, Baltis Llervu, and the great Nordic Warrior, Axel Iceblade, can fight off Dagon once more, before the Daedra Lord sets his unholy flames on Cyrodiil, Tamriel, or even Nirn itself.
With first-hand accounts from the survivors, soldiers, Llervu and Iceblade themselves, this is the most historically accurate book about the event that nearly overthrew the Empire itself.
It has been two years since Dagon attempted to overthrow the whole of Nirn, after the rogue daedra worshipers known as the Blood Axe Cultists combined blood and dark magicka together to summon the Daedric Prince of Destruction. During that time, Tamriel was painted with death, blood, destruction, and tragedy of indescribable levels. It was a blow that Tamriel would almost never recover from.
