The Voices had stopped.
This was the first thing Sanath Marko noticed since he had returned home with the stolen book. Having rested it upon his dining table, he paced in front of it, anxiously sucking on a lho-stick as he contemplated the ancient tome, thinking about the risks and rewards of reading such a book. He knew for sure that it had to be part of some mysterious cult, hidden away in the dark corners of Imperial society. If he were to read even a fraction of a page of such a book, it would mark him as a heretic for the rest of his life, branding him a traitor, for which the punishment could only be death. This he knew. What he did not know, and was thus eager to learn, was what the knowledge could be that would make it so damning to learn. This is why he chose to sit down with the book, cautiously opening the front cover, and doing his best to read the inscribed pages.
"Many in the Imperium follow a being known as the 'God-Emperor'. This being is more appropriately addressed as the 'Corpse-God', a feeble ruin of a man who pales in comparison to the true Lords of the Warp. There are four such Gods, each with a domain of power exclusive to them, which they watch over with immeasurable might, rewarding those who fulfill their wishes in the mortal realm. The first God to address is known as the Great Corrupter, capable of extending life, and destroying it, cleansing suffering, and renewing it. Not a fickle master by any means, he is quick to reward his followers.
The next God is the Lord of Blood, an honourable warrior of great martial prowess, who rewards the noble fighters, while shunning those who harm the weak and helpless. He is able to grant even the most minute of soldiers great strength and martial skill, allowing them to fell even the most powerful of creatures with one mighty blow.
Thirdly, there is the Architect of Fate. Devoted to obtaining all forms of knowledge and wisdom, his followers seek out lost libraries and crypts, searching for lost artifacts and and tomes, and seeking to spread the newfound knowledge. He honours those who serve him well by providing them with ancient secrets that benefit them greatly.
As the youngest God, the Prince of Pleasure lacks the talent and finesse of the other three, but is still a powerful ruler nonetheless. Gaining power from all forms of desire and love, he blesses his servants by fulfilling their innermost wishes and dreams..."
The Book would go on to describe rituals for pleasing each of the gods and other ways to service their wishes, though many of the pages were tattered, stained, or otherwise damaged. The information that did remain was confusing, and very contradictory to itself, and the benevolent descriptions of the gods. Sanath felt an urge to search for more info, which he suppressed for now. With the newfound knowledge swirling in his head like so many buzzing insects, he stowed the book in an alcove near his bed, then lied down and drifted off into a dreamless sleep.
