OK - well - I know there are other universes but I've never been to any, although I think I might be in a different one now, but where I'm from -
Image of the solar system, planets circling around the sun.
This isn't to scale, because actually the distances between planets and stars are really big, too big for me to picture properly. I live on Earth, the third one, that's the only one we know of in our universe that has any life on it. And then there's also Mercury - image of Mercury - which is small and very very hot during the day and very cold at night, and then there's Venus - image of Venus - and it's very very hot all the time because it's covered in poisonous clouds that trap the heat inside, and it rains acid there, and I think we've sent some probes there but it's not our favorite place to send probes because it's hard to see anything under all the clouds.
And there's Earth - Earth again - and it's nice - nicer than anywhere else, anyway - and it has oceans and forests and mountains and snow and volcanoes and lots of plants and animals, and - you told me it was where Quendi were from, actually, and that then most of the Quendi went to Valinor but then something bad happened and a bunch of them came back to Earth to try to stop it, and that's where humans are from, too.
And, uh, then there's Mars - Mars - and that's our favorite place to send probes, we've sent lots, we know all about what Mars looks like and sometimes we think about sending people to live there, except it'd be really hard to live there and it'd be really expensive and so then the government doesn't do it, even if we maybe know how.
And there's Jupiter, which is huge and made of gas and which has lots of little worlds spinning around it, all its moons - there are lots and lots but the biggest ones are Calypso and Ganymede and Io and Europa, and then there's Saturn, and it's big and gaseous and it has rings and it has Titan, where sometimes we think there maybe might be life, if we could get to it and see, and there's Uranus, which has less interesting rings and spins on its side doesn't have any cool moons, and there's Neptune, which has Triton, which is all frozen but it's cool because it has these geysers that I think spout liquid nitrogen, which is really really cold, and then way far away there's Pluto and its moon Charon, and then there are maybe other worlds even further away but we don't know much about them. And there are worlds that orbit different stars, too, but I don't have any of those ones memorized.
And that's all the worlds I know about. Unless you count the hell Lurconis is from, I guess. I went there once but I don't know how it's shaped.
