As the tide of Death magic suffusing the realms recedes in the wake of Teclis' retribution, Alarielle undertakes a grand ritual to seed the Mortal Realms with resurgent life energy. But with new growth comes the sundering of an ancient prison and the release of a forgotten deity – Kragnos, the End of Empires. Enraged by aeons of captivity, Kragnos' rampage across Ghur leads to the metropolis of Excelsis. Already tainted by the attentions of Slaanesh's servants, only unlikely alliances will save the city from its doom. The Broken Realms saga concludes in the fourth and final chapter. As the city of Excelsis comes under attack from Gordrakk's Waaagh! and Kragnos himself, it will take more than the return of a legendary Seraphon hero to turn the tide..
