After Drannenveldt, the leadership of the House of Morenth grew a bit frantic. They saw that the Jarramites, due to their commercial power, had a small measure of official tolerance, and they came up with their own plan to get a bit for themselves.
For years, Andrithans had been trying to rid Rang of both Morenthians and Polinakas. To secure the Andrithans' gratitude, Morenth began a twenty-one-year campaign, after which no one outside of bitty little hamlets would admit to being a Polianka worshipper.
At first, the authorities were pleased at this turn of events, but then they realized that all the people of Rang, not just Polinakas, were living in fear. Then, the Morenthians spread beyond Rang, and pressure came from other kingdoms to push them back. Before long, Rang was at war with nearly all the surrounding kingdoms, and with a good chunk of its own population, and there was civil war between Morenthians and Polinakas everywhere. That part was particularly bloody. Whole towns were left desolate.
By the end of the Plague of Morenth, there appeared to be no Morenthians or Polinakas left anywhere in the world. As it turned out, over fifty years later (751), the Morenthians were actually holding up in Maelbourg, Huerten (conquered in 748), and Haelbourg, Elgony (747), which at the time of the Plague, had not been part of Rang. At the time the Morenthians were found, the rulers of those baronies had other things on their minds, so they allowed the Morenthians to stay, but made it discretely known that the murder of a verifiable Morenthian outside those towns would not gather much attention.
