Where do you usually place Terra/Earth in your settings? In its own plane, or just as a normal world?
Or do you even bother with it at all?
I came across this while I was thinking about the cosmology of my campaign setting - I had thought of our universe having regions of space where magic is active, and much more space where it isn't (such as the Milky Way galaxy). Moreover, my focus world has some pretty sophisticated tech, so traveling there is not out of the question.
While Urbis closely echoes many aspects of Earth history, on the whole I prefer to keep them seperate. The setting is strange enough as it is.
However, in my current Exalted campaign, modern-day Earth and Creation co-exist in the same universe. In fact, three of the characters come from there!
I would have earth as seperate from the magical areas, but with "weak spots" that interconnect so magic is available on parts of earth as well.
Altvogge is a geocentric reality, with the Altvogge Sphere at the center of the well-defined universe. Not such thing as Terra.
Nordica takes place on Earth.
As for the Jade Stage, Earth's treatment is up to interpretation, and the "true details" are left intentionally vague. Is it an "alternate material plane" floating elsewhere in the Void? Maybe. Is a 17th century Earth actually Indirai? Perhaps.
A friend of mine who has been reading over the Jade Stage for as long as I've been writing it suggests that perhaps the original humans to arrive on dojh-oln-beh were actually the Lost Colony of Roanoke, North Carolina, who tracelessly vanished. Again, I won't comment, other than to say it's a really cool theory.
Earth is left intentionally vague in Red Valor, although the only planet that is defined is the world of Perann. If someone wanted to introduce Terra, that option is open.
In the Stars Above, Earth is actually a central part of the Interplanetary Alliance.
The universe that contained Earth has been "recollapsed".

My Terra is in an alternate universe, and I havent' worked out how precisely the planet functions, or if indeed it is a planet. Human beings came through a dimensional rift by pure mistake and invaded it like some kind of virus.
Earth simply does not exist in ym settings. I lack enough of an undertsnading of it's history and mythology to successfully add it to any world I make, and I find it ratherr dull overall. I write fantasy, not speculative fiction.
In my early stages of messing around with Ere, Ere was Earth, following a cataclysm that undid a previous event that had knocked the world out of phase with 'Magic Space' and into 'Real Space'.
Now though, Earth is part of the Expanded World and simply happens to be blissbully unaware of how easy it is to abuse metaphysics. Without magic being manipulated, no 'background magic' could give rise to magical beasts.
In my campaign the Earth was where humans came from. It is just one of an almost infinite aspects of the same world spread across a multitude of dimensions. Our Earth, the Earths of the Dwarves, the Orcs and the Giants were melded together by spirits together to form the Great Land, which is the source of most human mythology. The Great Land eventually tore itself apart, causing disasters on all the homeworlds. In Earth's case the sea levels rose dramatically (the Holocene)to drown Earth's 'pre-ancient' civilizations. The Terra of my campaign is exactly what it is now - a small boring world almost devoid of magic, a place no where near as exciting as it used to be. Planar travel to Earth has been impossible for the last 11 000 years. The real action takes place on Eda, a fragment of the Great Land that survived the Sundering
