Sanctum Book Three: Forgotten World by B. K. Moe continues the story of Sanctum Part Two: Shattered World and Sanctum Part One: Pestilent World and recounts the final confrontations of the Darkening, when the grand alliance of humans, Sun Elves and Kessver march against the Arch Magister.
The siege of Warakk is lifted, but the cost was nigh unbearable for the remnants of humanity. Now the free nations of Erathia have assembled what fighting forces remain to muster against the source of the continent's desolation. Humbled by the odds arrayed against them but knowing there is no other choice but to try, Ostrava and Alena join the monumental endeavour to take Erathia back from the Arch Magister, determined to see things through to their conclusion.
One way or another, the Darkening ends.
