NOTE: I imagined this map to be made by the Imperial Geographical Society of the Mede Empire, about a century before the events of Skyrim. So keep the "unreliable narrator" in mind.

Flags of the Fourth Era:
CONTINENTS OF NIRN
Source: A Pocket Guide to the Empire, 3rd Edition, Chapter: Other Lands
Tamriel: The continent that all the Elder Scrolls games take place on, and the only continent where official maps exist (except for post-catastrophe Yokuda).
Yokuda: The original home of the Redguard. The majority of this continent sank into the sea for unknown reasons during the Fist Era. A map of Yokuda (after the catastrophe) can be seen in The Elder Scrolls Adventures: Redguard (1998).
Akavir: A continent lying to the east of Tamriel. It is the homeland of four races collectively referred to as the "Akaviri," which is composed of the Snow Demons of Kamal, the serpent-men of Tsaesci, the Monkey People of Tang Mo, and the Tiger Dragons of Ka'Po'Tun. Little else is known about the continent.
Atmora: A frozen continent located far to the north of Tamriel, across the Sea of Ghosts. It was home to a race of men known as Atmorans around the Merethic Era. The legendary Ysgramor and his Five Hundred Companions came from this continent.
Pyandonea: Home to the elusive Maormer (Sea Elves), This island-continent is covered mostly in dense rain forest.
Aldmeris: Very little is known of the alleged Elven homeland, and it is often considered to be merely a myth. Its location, environment, politics, religion, and even its current existence are matters of conjecture.
About the size of Atmora:
It's not actually as large as it looks on the map, it's a result of the Mercator projection.
Here you can see an example of how the Mercator projection distort landmasses to the far north and south on a map:
I can actually forgive the inclusion of Aldmeris here, as historical maps hap non-existent “continents“ such as Terra Australis all the time. This is a really cool map, my guy! Well done! Really captures Nirn in a way I don’t see often enough.
I am very sorry, but I must strongly criticize this map.
First of all - this is not a Mercator projection (see 3).
Linear scale - works only at the equator. Every other parallel is shorter, as the top edge of this map measures zero kilometers long. If it works at all in this case because the divider at the equator has a different length than diveder on linear scale.
Compass rose. The geographic coordinate grid suggests equidistant cylindrical projection. On such a mapping, only four directions are preserved (NESW). The rest do not match.
The land at the North Pole is drawn in violation of all rules of cartographic art. The east side should end at exactly the same latitude as the west side.
Technically, he put all known continents on there as Lyg is some kind of reflection of tamriel. Whether a failed world or something else. And Kirkbride mainly said that the elder scrolls show no signs of an Aldmeris but there are, while few, some things that can be blind to elder scrolls. For example, if the land is separate from time. This is why dragon breaks do not show up. And with the Elves connection to the Gods and mainly akotosh, it is possible that their homeland was hidden, even from time itself. Either way it is an amazing map and no matter how you think the world of nirn is placed, you can still appreciate this amazing work of art.
Out of curiosity, how did you think of how Akavir and Pyandonea might look? Is there anything to indicate them having shapes like this in the lore?
