As the war which consumes Dervelai drags on

Algarve's reserves become more and more stretched. King Mezentio undertakes war on many fronts, and his main armies become sucked in to the huge landmass of Unkerlant, their main enemy. As conquered races are inducted into the Algarvian army, their fighting edge softens, and swift victory becomes ever more necessary, leading to the sacrifice of more and more Kaunians to allow Algarvian mages to create ever stronger blood sorcery.

Meanwhile, the mad King Swemmel of Unkerlant

orders the death of thousands of his own subjects in an attempt to match the magecraft of Algarve. But the most deadly magic of all is taking place on a small island, where the ultimate weapon is coming slowly to fruition.
