The full inscription previously read, "The hand of Ba-Ka extends beyond death itself." The name Ba-Ka (also Hellenized as Bikheris) refers to a Pharaoh of Egypt during the 4th Dynasty around 2500 BCE, who ruled after Khafre, and before Menkaure, according to the Turin King list. Current knowledge of Ba-Ka in the Egyptology field has been challenged by Foundation-implanted archaeologists in an attempt to suppress active knowledge of Ba-Ka. Primary source documents and other knowledge of Ba-Ka that survived the initial Egyptian purge have been altered and otherwise tampered with to erase knowledge of Ba-Ka. All inscriptions in SCP-1644 containing his name have been erased. Erasure or acquisition of all sources known to reference Ba-Ka is to be considered a primary means of containment for SCP-1644.

During scheduled excavation, a series of papyrus scrolls written in hieratic were found in the northwest region of SCP-1644. These scrolls have been organized here in what researchers have deemed is the correct chronological order. The content of these scrolls was deemed sensitive after review by the supervisor of SCP-1644. All personnel below the clearance of 4/1644 who were aware of these scrolls were administered Class-B amnestics. The content of the scrolls has been transcribed here.

Long live the true Pharaoh, Ba-Ka, He Who is the Soul and Life of the People. The false Pharaoh, Menkaure, sits upon a throne of deceit, and he shall be overthrown to make way for the true Pharaoh when the gods smile upon us. The people have been turned against the true Pharaoh, but we will wipe away the false Pharaoh's lies.

We remain at the last stronghold, far away into the land of the setting sun. The false Pharaoh will not find us here.

The Pharaoh has gathered his most powerful mages to see the way forward. No false Pharaoh can stand against the power of the divine. This false believer who has decried our arts will suffer the consequences of his heresy. Praise the true Pharaoh. His name will live on in glory, and his reign will be forever remembered for its defeat of the unholy.

Hekuhirkopshef, greatest of the Pharaoh's mages, has come forward, and proposed something to the Pharaoh. Something in his book of magic holds the way forward, he claims. The other mages do not trust him, but they cannot deny his cleverness, and the power of his book is beyond their reach.

This ritual that you have proposed is of an immense cost. I do not have enough innocents to sacrifice, as you have stated is necessary. I can only substitute the blood of others, which should suffice for this ritual. Surely your book cannot be so narrow as to prevent this?

If the ritual continues as you have stated, you shall be rewarded with the finest riches once the throne is mine again.

The True Pharaoh, Ba-Ka, He Who is the Soul and Life of the People.

This ritual contains some of the most powerful magic in the world, great and mighty Pharaoh. The gods will be satisfied by the sacrifice, and eternal life shall be yours, if and only if you follow the ritual exactly. The ritual itself shall not be difficult. Fear not. The power of my magic has already given you the charm to ward off false believers, a testament to my strength. Potent magic as to twist the minds of men is magic of a degree beyond the reach of most of your petty illusionists, who could not begin to fathom the first page of the book of power.

Hekuhirkopshef, He Whose Strength is Magic, and Keeper of the Book.

We will never agree to this ritual, Pharaoh. Consider this a petition and formal letter of complaints. This is nothing less than a blasphemy against the gods themselves. Eternal life was not meant for us, and no sacrifice shall placate the wrath of the gods, once a soul has been denied to Ma'at and Osiris. We remained with you when Menkaure rose up to denounce you, but we cannot stay silent at this travesty.

High Priest Menmaatre

By the imperial decree of Ba-Ka, true Pharaoh of the Twin Kingdoms of Egypt, all priests who have signed this recent open letter of rebellion have been seized. These priests sought to challenge the authority of the son of the gods, and this is nothing less than heresy. They will be dealt with swiftly, and with punishment befitting their heinous crime.

Imperial Decree of Ba-Ka, He Who is the Soul and Life of the People.

The ritual site is being established. The mage stated that here, deep in the heart of the land of the dead is the only point in which it could happen. There is no other location in which such a ritual could ever be attempted. The sacrifices have been made ready, and the once-holy nature of such sacrifices should placate the gods. Osiris will have his souls.

Praise the Pharaoh, Ba-Ka, He whose reign shall last for generations; He who is the shatterer of heresies; He who possesses the wisdom of Thoth, and the strength of Horus; He Who is the Soul and Life of the People.

This ritual cannot be completed as you have demanded. I cannot acquire the blood of innocents, nor am I willing to give it. The gods will have to accept blood that is not wholly pure. There is no other option available. I must proceed with what I have. The pretender's forces cannot be kept away forever, and the illusionists' charms will not hide us indefinitely. I feel death coming. I cannot wait any longer. I shall be buried soon, and the ritual must take place.

The True Pharaoh, Ba-Ka, He Who is the Soul and Life of the People.

Then prepare for the consequences of failing the gods, Pharaoh. The book of power does not lie. It speaks the only truth in this world, the truth of power and magic. I can say nothing more. May the gods have mercy upon your soul.

Hekuhirkopshef, He Whose Strength is Magic, and Keeper of the Book.

The mage was right. The gods were not satisfied with the sacrifice. Ma'at is furious that her scales have been robbed. Ammit is unleashed upon this world, and the unholy plagues of the gods have descended upon our stronghold. The mage is gone, and his promises of eternal life are as well. The Pharaoh yet slumbers in his tomb, hidden away from the eyes of the gods and men. Ammit's rage seeks to devour us all.

The gods will obtain the innocent blood that they desire, one way or another.

Do not pray for deliverance. Prayers are futile when the gods themselves are wrathful. There is no salvation.

We are guilty men, and the gods will destroy us for our impudence.

Knowledge about SCP-1644's true primary purpose as a ritual site is to remain to individuals of Level 4/1644 clearance and above. If an individual without proper clearance becomes aware of SCP-1644's true purpose, it is to be considered a containment breach.

Acquiring any information about the book referenced in several of the volumes is considered to be of the utmost importance. All documents that reference Ba-Ka are to be scanned for further information concerning such a book, and then are to be destroyed in order to prevent possible links to the book, or the figure known as "Hekuhirkopshef," who is referred to as the keeper of the book.

Currently, the only personnel stationed at Outpost-126 who are aware of SCP-1644's true purpose are the current supervisor, and the deputy supervisor.

The following document was also seized from the excavation of Menkaure's tomb, following its discovery by archaeologists. All individuals coming in contact with the document were issued Class-B amnestics.

The blasphemer king, Ba-Ka, has been overthrown, and his magic rituals and blasphemy against the gods has been overthrown as well. No mention of his rule will ever occur. I demand that all information about Ba-Ka be erased, and that the remaining officials during his time be executed immediately. His stronghold will be destroyed immediately, and his corpse shall be scattered into pieces and burned for his heresy. This plague that he has unleashed will be crushed swiftly.

The chief of his blasphemies, Hekuhirkopshef, is to be found immediately. He shall be cut to pieces, burned, and fed to the Eastern desert, forever out of reach of the land of true salvation. His book must be seized, and brought to me.

May Thoth's wisdom guide us forward, and shatter the blasphemer's ways.

-Imperial Decree of Menkaure.

On 10/8/██, in order to acquire more information about the sarcophagus, the then supervisor of SCP-1644 ordered a CT scan. While examining the images of the CT scan, an error was noticed that caused blurring of the image. Following 2 more tests that featured the same blurring, Foundation radiologists confirmed that the blurring on the image was consistent with movement in the interior of the subject of the scan. All radiologists involved in this test have been issued Class-A amnestics.
