# D&D GeneralToril must be a Super Earth.

Let me try to explain myself better. Earth’s circumference is roughly 40,075 kilometers. A point on Earth’s surface at the equator covers that distance in 23 hours and 56 minutes, meaning it is traveling at around about 1656 kilometers per hour. Mars’s circumference is roughly 21,344 (a little over half the size of Earth), but it’s rotational period is actually longer than Earths by close to 40 minutes. A point on Mars’s surface at the equator is therefore traveling a little over half the distance that our point on Earth is, in a little over the same amount of time. Therefore, it is spinning much slower. 868.22 kilometers per hour to be precise, a little over half the speed.

If Mars were the size of Earth but still spun at the same speed, its day would be over twice as long as Earth’s. If it was the same size but spun as fast as earth did, it’s day would be a quarter the length of Earth’s.

Yeah but that is only the velocity vector of a point on the surface, which says nothing about the day length.

Since you do not notice this velocity vector because it does not affect your own relative velocity, in other words everything around you moves along with you on this vector it is less useful to describe the planetary environment.

This does effect things like gravity though, the faster some planet spins the lower the gravity because the
centrifugal force vector opposes the gravitational force vector.

Also the mass of the planet of course determines the gravitational force. On the moon it is only about 1/8 of earth for this your body only weighs 10 kg if it weighs 80 on earth. So you can jump incredible wide and high.

That map is home brewed stuff.
Of course we don't need a homebrew map. @Salthorae already provided cannon evidence it is a class E planet similar to earth and @TwoSix provided evidence of the land area suggesting it is not a super earth. Of course, you could just ask Ed now that he is posting monthly articles on this site.

Who proves now that toril is in reality flat and we are all wrong?
And at which armory were do we get tinfoil helmets in that case?

Doesn't look that big. Superimpose Faerun onto Western USA.

I did the math once, Athkatla to Neverwinter is roughly the distance between Los Angeles and Seattle (give or take around 50 miles). If you actually smoosh all of Faerun into North America, Europe, and Asia it more or less fits.

Class E includes the lower end of Super Earths, Earth has 12000km of diameter roughly, a class E can be as high as 16000km in diameter, which is low end of Super Earth territory. And Toril got it's class E status BEFORE the Spellplague and Sundering changed the Planets dimensions, Abeir traded continents back and forther and AO straight up added more wilderness making Faerun larger during the Sundering, that is canon as odd as it sounds.

You mean it takes 3 earth continients to fill the same space as Faerun alone? And Faerun is only the second largest continent on Toril, Kara Tur is like twice as big or close.

Interestingly enough neither Toril nor Abeir or even Glyth are the largest planets in Realmspace. Coliar is an inhabited gas giant, filled with floating islands and air. Elminister has a huge spherical fortress there. It's inhabitants are mainly Aacrokocra, Lizardfolk, and Dragons.

The definition of what makes a planet a super-earth is not set, but it seams to me the intent of the class-E was to be earth-like, not super-earth. Though to be honest, I have no idea why the definition even matters for a fantasy world, or why this is a thread, or why I am participating in it!

Nah, I mean including Kara-Tur and stuff. The whole land mass that contains everything conneted to Faerun an Kara-Tur is the size of North America, Europe and Asia combined. That leaves Africa, Australia and South America for the rest.

Edit: and Antarctica.

Linear speed of a point on the surface, yes. Angular speed of a point on the surface, not so much.

Units matter.

I assume that includes Zakhara.

The maps never show the polar ice caps assuming the Forgotten Realms has them, which it should, so far now I'm leaving out Antartica.

The leaves Osse, Maztica, Archrome, Katashaka, and maybe Laekrond if it didn't go back to Abeir. (We know Maztica came back from Abeir, but it is ambiguous if Laekrond went back to Abeir or if something stopped it from returning, but adjusting its position on Toril.

Totally true. I'm mostly just poking fun at these settings mostly being fantasy European medieval, which means that a lot of that wilderness should be miles upon miles of farmlands with several little villages (albeit not all necessarily anything we would recognize as such today) coming by every few miles. It should take days to get anywhere, but there should be a lot more people and civilization along the way than I usually see presented. All usable land should basically be claimed and settled to the extent that threats of magical evil allow.
That is very early modern of you.

Clearing forests and swamps and the like take a lot of work. Getting positive ROI from the investment to clear such land can take generations.

Machines make this easier.

Now, a farmer near some unimproved land might take their surplus and invest it in improving it, or a noble might do the same.

But in general, the land you improve is the easiest stuff to improve, and only when the cost of clearing is low enough do you consider improving marginal land. Eventually the remaining forested land is poor land even after you clear it; you can get a crop off it with fertilizing, but the next year it is garbage and you have to return it to wood.

I'm just assuming available land mass. Antarctica is a land mass, it just happens to sit on a polar ice cap, although at one point was attached to Australia. And while the FR maps don't show the entire ice cap the Endless Ice Sea to me is pretty clearly supposed to be the southern edge of an ice cap.

The only thing I need to know is what is toril’s gravity. and how much would I be able to lift and how far could i jump If i took a portal to Oerth. Also how fast could I run. Because I am thinking of creating a character on faerun and hopping a gate to either oerth or Mars.

80-95% of the populations of every pre-modern agrarian society was working whatever land could be worked. In the Western Medieval milieu that traditional fantasy draws heavily upon there would indeed be plenty of "wastes" (or "deserts" as they would often call an inhospitable mountain or swamp). But even these spaces were usually being used to graze some cattle, collect firewood, kept as royal forests, etc. by the denizens of the nearby farmlands. In many contexts they would be communal manor lands that weren't exactly owned in a modern sense (though the lord and the sovereign would both have claims). In most places you would never be as far from civilization as is routinely portrayed in our fantasy versions of these places. That goes doubly for any context where you are on a road.

Most fantasy worlds are weirdly empty, usually to a point that makes the infrastructure portrayed for whatever civilization they do have make little or no sense. I blame Tolkien; Minas Tirith should have been surrounded by farms. But, of course, there is far more adventure to be found in wildernesses, particularly when someone conveniently built elaborate dungeons all over the place.

As I also noted from the Realmspace supplement, Toril's oceans only cover 60% of the planet's surface as well.

So even if Toril has more available landmass, I'd be surprised if it'd be more than 15% difference accounted for between their ocean coverage and the Earth's 75% coverage.

Also - @gyor where is the reference to Ao adding landmass?

It’s best to forget the “cannon” (like that matters) and use the 2e maps to determine size.

The forgotten realms atlas has a nice map of the globe I think.
