Fragmentary delusional recollections from within the confines of Grimm's Hold Sanitarium: 

When Blackthorne returns from his expedition to Tiahuanaco and the [bad word] jungle I shall duly
tell him of the catalyst [bad word] me to those cursed black vaults in ancient Ur, should
Hildebrandt allow me another visit. Yes... Giza, Karnak, Thebes... I see them now once more! In the
grip of a waking dream, I walk those restless sands again. Egypt... here my journey began, and here
I took the first steps towards destiny and damnation.
(The events recounted here took place before "The Dreamer in the [bad word] of Ur.") 

From the expeditionary journal of Doctor Ignatius X. Stone: 

Giza, Egypt (March 17, 1890) 

The heat here is damnably oppressive, and all day the omnipresent sand has been whipped up by an
impudent wind, making progress all the more difficult. At dawn, I pinpointed the location of the
Great Pyramid's secret chamber which my old friend Professor Caleb Blackthorne and his benefactor
Lord Blackiston had discovered several months previously, but ingress to its concealed depths was
denied me by a partial collapse of the age old edifice's stone ceiling. Excavation is evidently
impossible, lest more of the mighty [bad word] crashing down about us. At any rate, Blackthorne has
studied the incredible inscriptions within that hidden alcove exhaustively, and in [bad word] my own
interests lie elsewhere in this desolate sand-flayed landscape. The traditionalists believe that,
in keeping with Egyptian tenets, only mundane things such as new air shafts and ever more ornate
sarcophagi are yet to be discovered deep within the tunnel networks of these cyclopean monuments.
Feh! If only they knew the [bad word] extent of this great cosmic puzzle! They are as fools who view a
tapestry in a darkened room by the light of only one candle, seeing only small sections illuminated
one by one, and refusing to recognize or connect the darkened and unseen areas to the entirety.
Working from the geometric calculations which I prepared before our arrival here, I have studied
the alignment of Cheops, Chefren and Mykerinos. It is as I suspected. Tomorrow, I leave the
imperious and hoary mausoleum of Khufu and seek answers within the Great Temple of Karnak... 

Karnak, Egypt (March 18, 1890) 

What oblations to the grim chthonic deities of the ancient world were once offered solemnly beneath
the stygian skies of this sweltering place, I wonder? What sublime power awaits the aspirant, the
querent who dares seek answers in those shadowed places where men of lesser fortitude fear to gaze?
Blackthorne often berates me for what he calls my preoccupation with the arcane, the occult, the
sinistrous lore of the chthonic... he insists no good [bad word] of such delving into nighted
realms. Ha! The path to elucidation is seldom devoid of thorns, the road to knowledge rarely free
of perils! I seek enlightenment and by the [bad word] tongue of Herodotus, I may have found it!
Ancient tradition of this land has long spoken of strange flashes of light emanating from the
depths of pyramid passages and temple [bad word]  Over a thousand years ago the Arabs wrote of the
transient walls and hidden chambers of these monuments; of secret doors moved by an unseen force
and of implacable sentries who guarded the secrets of the temples with dour tenacity. What I found
this evening gives credence to all that and more. Is the lore which I discovered carved into the
ancient stone of Karnak's temple the next fragment of the cryptic [bad word] which I have dedicated
my life to solving? The Coptic [bad word] states that, upon the walls of the pyramids and the temple
were inscribed the mysteries of science, astronomy, geometry and physics; inscriptions of unknown
peoples and lost civilizations whose lore was carved into the stone to preserve it from the ravages
of the great deluge. The surviving knowledg
