The parchment was obviously made from dried skin as Khalid observes it.
The ink, blood and a combination of ash of the dead and internal fluids.
It seemed to recount the fact that its writer who signed the pages Kas in earther had found in the Cursed Ruins an ancient armory. In that armory he discovered a set of books. These books were stolen goods, first taken by the Kias from the Nightmare Lords, then looted by the Sea Kings in the final days of the Kias wars.
The words written in blood bile and ash told a sad tale. A tale of a man whose love for God was his only focus. Yet his friends in the Inquisition pulled strings and promotion after promotion came Kas’ way. Soon he was a Bishop leading young men to spread the word as revealed by the Cardinal Bray at the founding of Refuge.
Then he led the army away from Karov and the beautiful wooden city and its miles of thatched roofs, far too happy to cleanse the world of demons which is what he genuinely thought Olgogs were.
He did so to strike a decisive blow against the haven of evil called Tla’loc’al. While he was away so many of his innocent parishoners were killed off by the Flamewinds.
He returned to this lab deeply saddened, feeling a failure. Kas again searched for a weapon which could wipe out the Olgogs. After passing through many a glowing doorway and many a swirling bridge he discovered a weapon that he somehow knew would help him.He found an alien claw crafted into a gauntlet. It whispered into his mind as he slept communicating through dreams. He knew that now. Then he had thought if gods visions could be so vivid surely he had to find out the truth.
Throughout those days he opened the books and read from their dark pages. He learned of the rise of the Warmonger and the shattering of the Great Four Ancient Evils powers and trapped them in the hell dimensions.
Kas confronted the Inquisitor friends he had once considered his peers and demanded to be brought to Pope Cristos Dugari.
Kas learned in that meeting that their faith had been founded by the Kias Domino.
He was offered to be inducted into the inner circle of the Inquisition who all knew this horrific and disturbing flip side of the Church of One.
The pages ended describing Bishop Kasanth Dannor taking all citizens who cared to come with them, survivors of the war scarred by their former faiths zealous attack on the innocent Olgogs. They would travel north and torture all who ascribed to the false hateful faith of the Church of One and through their blood sacrifice gain power over the Leyas as the books described.
When they reached the City of the Gods, Khalid would know the Bishop Kasanth joined forces with Lord Camarel and start the Church of Shadows.
