Sorry about that, I was to eager to write the place that I forgot about the alphabet!!

King Arthur's stable.

Lilliput.....

Mount Olympus

Nowhere AZ , don't see one listed on a state map.

Og, Ered Nimrais

Oof, this is harder than it seems.

I've going to cheat (kindof).

Peldvale, is a boggy area in an AD&D game called Baldur's Gate.

Atlantis was invented by Plato some time during the 16th century. There have since been several contenders of cities that had become completely flooded and lost to history, but since there were no records of these places before the 16th century and no evidence that Plato had access to information that no one else in the world did then it's a safe bet Atlantis was a made up island named after the Atlantic Ocean.

But, I don't think we should completely rule out ancestral memory. For example, many of the stories in the bible can be traced back 1000s of years before Jesus was born, for example the Great Flood was well known long before, and perhaps it was even the flood that buried the region that later inspired Atlantis.
