Maps of Laterre

Hi MMB, I am a cartophile. Here's an update of a post I sent to the MML awhile back.

CAS's Averoigne Cycle is explicitly set within the shared-world of
H.P. Lovecraft's Cthulhu Mythos. Therefore, "Laterre" would simply be a Mystarocentric
term (French/Sylaire-derived) for "Cthulhu Mythos
Earth" (an OOC term). The Mystarocentric term for the
entire "Cthulhu Mythos Universe" would be the "Dimension of Myth".

Here's a compilation of maps of various places of Laterre through the ages:

Hyperborea: Laterre's Greenland pre-750,000BC
(described in a CAS story cycle). No known relation to
Mystara's similarly-named region of Brun, or to the
land of Hyperborea of Laterre's later Hyborian Age
(the Hyborian Hyperborea is the ancestral land of the
Laterran Finnic peoples). Here's a couple maps of Laterre's
ancient continent of Hyperborea:

Thurian Age: Laterre, c.20,000BC. The age of Robert E.
Howard's Kull of Atlantis. For a map of Thurian Age
Laterre (including Atlantis), see:

Hyborian Age: the Old World of Laterre, c.12,000BC. The age of REH's
Conan of Cimmeria and Red Sonja of Hyrkania. For
roleplaying resources, there's a the new d20 RPG by Mongoose, a GURPS Conan
sourcebook, and short-lived TSR-produced Conan and Red
Sonja games. For maps of Hyborian Age Laterre, both continental and regional, see:

Poseidonia, the last remnant of Atlantis, sinks c. 9,500 BC; featured in CAS stories:

Averoigne. Laterre analogue of the medieval province of Auvergne in south-central France: (showing the province w/in France as a whole) (a map of Castle Amber)

Modern Laterre: At this late stage, Laterre's
geography would now more or less parallel RW Earth's.
The d20 and BRP "Call of Cthulhu" rpg cover three modern
Laterran decades: the 1890's, the 1920's, and the
1990's. There's also a Steve Jackson Games/Chaosium
crossover GURPS guide called "Cthulhupunk", which
would conceivably portray Laterre in the 21st century.
Maps of the town of Arkham are available here:

Xothique: A continent from a CAS story cycle in
Laterre's ultra-far future, resulting from the subsidence and uplift of the southern continental landmasses. For maps of Xothique, see:

Finally, here's a map of the Dreamlands, which not physically part of Laterre, is psychically accessible from Laterre:

P.S. Shawn, could this compilation be kept in a Laterre section of the Vaults?

Also, while we're at it, Averoigne is directly referenced in the League of Extraordinary Gentlemen, v.2, in the almanac-style entries at the end of the book. So there's that tie, fwiw.

Worlds of Cthulhu #2, Worlds of Cthulhu #3 and Worlds of Cthulhu #4 have articles on Averoigne. Presumedly #1 does, too.

Thanks for the links ripvanwormer. I'd like to read their geographic overview of Averoigne.
