Murtuy ka Varha (concept)
The Murtuy ka Varha was the second and perhaps most devastating of the Chan Skorpokaipis (Four Apocalypses) which nearly destroyed Kashirya between the 9th and 11th centuries.
Beginning in the 9th century with the Discovery of the Adiyya ka Pharvaarava by the Vidvaookeyatran scholar Navad Javhad, who proceeded to widely distribute dozens of exceptionally dangerous rituals and spells he had discovered despite the clear risks involved. Within a year of this, cultists would use the rituals to raise legions of spirits and other undead, which they immediately lost control of. During this, Javhad continued to distribute the works while also insisting that the apocalyptic events were not the fault of his work but the fault of those not ready for such great knowledge.
The war reached its apex with the rise of the Lich-like Satayan Holkkarak who directed the armies of the dead against the rest of Kashirya and only ended with the Death of Holkkarak and the End of the Murtuy ka Varha.
