Extra special thanks to Daniel Harms, for his two Encyclopedia Cthulhiana reference books, as well as his additional help. The superb Encyclopedia Cthulhiana works (especially the 2nd Edition) were the main source for this Timeline, and excellent texts on top of that! Check out his website, The Necronomicon Files.

Much of the earliest events and certain events throughout the rest of the Timeline are derived specifically from Shannon Appel's excellent "Timeline of the Cthulhu Mythos" in the Encyclopedia Cthulhiana 2nd Edition's Appendix D. Further useful timeline information for game events was graciously provided by Lynn Willis.

I also give thanks to Daniel Harms, Guy Bock, Geoff Burling and docsavage80, who brought to my attention several necessary corrections and clarifications.

Of course, thanks also go to all the great Mythos authors, especially H.P. Lovecraft!

5 million years ago: The Serpent People city of Yoth flourishes at this time under the guidance of their god, Yig. Their science has progressed to the point that they have created servant species, such as the gyaa-yothn and voormis. However, Yoth is destroyed by Yig when some of the Serpent People turn to the worship of Tsathoggua. A few Yig-worshipping survivors found a new civilization in Hyperborea.

Some great human sorcerers, including Zon Mezzamalech, live in this short-lived kingdom. The human civilization of Zobna falls next, moving to Lomar in the south and destroying the native cannibal gnophkehs.

c. 9550 BC: A final cataclysm destroys the Hyborian world and rises new land masses, moving the world into more or less its modern configuration. Portions of the Hyborian continent, Poseidonis, and Mu all sink beneath the waves. In later times, this event is remembered as the Great Flood. ("The Hyborian Age," Howard; "Timeline of the Cthulhu Mythos," Appel)

The lloigor scatter across the world, settling in the Middle East, New England, Wales, and elsewhere. ("The Return of the Lloigor," Wilson)

The Black Lotus is taken from the collapsing Stygia to the Plateaus of Leng and Sung, where it continues to be cultivated. In the remnants of Stygia, the Vanir found the country of Khem. ("Dope War of the Black Tong," Price; "Black Eons," Howard and Price)

The Brythunians emigrate to a land east of Khem and become the priests of Mitra, keeping their bloodline pure and separate from the local population. (The Winds of Zarr, Tierney)

c. 16,000: The wizard Nug-Soth is one of many across time who exchanges minds with one of the Great Race of Yith. ("The Shadow Out of Time," Lovecraft)

The Far Future (c. AD 8,000,000?): The time of Zothique, last continent of Earth, and home to the dying remnants of the human race. The culture is on a barbaric level, and magic has become dominant over science.

c. AD 18,000,000: A "half-plastic denizen" of the interior of a planet beyond Pluto is among those that exchanges mind with the Great Race of Yith. ("The Shadow Out of Time," Lovecraft)

c. AD 50,000,000: Following the final end of humanity, a new race of beetle-like insects arises. These are possessed by the Great Race of Yith, leaving their previous home on a planet orbiting a dark star near Taurus. Eventually, even the beetles die out, and the Yithians send their collective minds into a vegetable species living on Mercury. ("The Shadow Out of Time," Lovecraft)

c. AD 500,000,000: The first primitive life develops on Venus. One Venusian is among those that exchanges minds with the Great Race of Yith. (The Transition of Titus Crow, Lumley; "The Shadow Out of Time," Lovecraft)

The Further Future (c. AD 1,000,000,000?): The last inhabitants of Earth, a species of arachnids, live within the interior of the dying world. ("The Shadow Out of Time," Lovecraft)
 

Internal Inconsistencies and Consequent Reconciliations in the Data from the Encyclopedia Cthulhiana (2nd Edition):

• This particular section should be omitted in the version printed in the Call of Cthulhu core rulebook- it is only to establish contradictions and corrections for the Encyclopedia Cthulhiana and nothing more.
• The year of the destruction of Blowne Manor is given as 1968 in Crow, Titus and 1969 in de Marigny, Henri-Laurent. I chose to use the latter date since it's ten years before de Marigny's reappearance.
• The date of Khem being taken over by alien-human hybrid pharaohs is stated as around 7200 BC in Appendix D and the eighth century BC in Khem. I chose the former date because the latter isn't even internally consistent (perhaps they meant eightieth century BC, but that's 700 years older than the date in Appendix D, and six generations would hardly stretch 1000 years).
• Golden Goblin Press states that The Shadow Out of Time was written by Wingate Peaslee; however, the entry on Peaslee, Nathaniel Wingate states that he wrote it. According to Mr. Harms, Wingate Peaslee was the author.
• The year of Justin Geoffrey's visit to Xuthtlan is given as 1921 in Geoffrey, Justin and 1922 in People of the Monolith, The. I chose the former date, because it was stated in the entry of Geoffrey himself, and the other entry is not focused on him.
• Nug-Soth states that the wizard hails from 14,000 AD; however, "The Shadow Out of Time" states the year as 16,000 AD. I went with the original source.
• Allen, Zadok states that he disappeared in the summer of 1926. However, he disappeared after Robert Olmstead talked with him on July 15, 1927, according to Olmstead, Robert Martin. Numerous other entries correlate the latter date, so I have chosen to use it.
• In the Phillips, Winfield entry, it lists him as living from 1907-1937; however, in the entry itself it states that he died "a year later" than 1929 (1930). I followed the entry text, and assumed the 1907-1937 text to be a simple error.
• Glaaki states that its cult disappeared in the 1860s; Revelations of Glaaki states that they disappeared in the 1870s. I chose the former entry's data because it focused on the source, rather than a work based on it. However, since Revelations of Glaaki was printed in 1865, I narrowed the span down to 5 years rather than 10.
• The Shining Trapezohedron entry states that the events of "The Haunter of the Dark" took place in 1934, but Blake, Robert Harrison and Dexter, Ambrose both state that the story took place in 1935. Majority rules.
• Derby, Edward Pickman states that Azathoth and Other Horrors was written when Derby was 18 (1910 by my chronology); however, the entry on Azathoth and Other Horrors itself contradicts this with both its possible dates, 1916 and 1919. I included all three possibilities- perhaps the 1910 printing was self-published.
• Arkham says the 1905 epidemic was of cholera; West, Dr. Herbert states that the epidemic was of typhoid. "Herbert West- Reanimator" confirms the latter.
• The entry for Sanbourne Institute of Pacific Antiquities states the more likely date of its closing at 1931, and states 1933 as an alternate. Zanthu Tablets confirms the Institute was still active by 1933, so I chose that year.
• Pánfilio Zamacona's first name is "Pánfilio" in K'n-yan and "Panfilio" in Zamacona y Nuñez, Panfilio de. According to Mr. Harms, "Pánfilio" is the correct spelling.
• The events of "The Colossus of Ylourgne" are given as taking place in 1232 in du Nord, Gaspard, but the text gives the date as 1281.
• The climax of "Out of the Aeons" is stated to occur in 1931 in related entries, but the story says 1932.
• Regarding the Necronomicon- I decided to ignore the listings in Appendix A that contradicted the majority, gave unnecessary explanations, or added unnecessary complications, including those of the following years: c. 1000 BC; 850; 1487; 1929; 1932; 1972; 1977; 1978.
