Editing Nobledark Imperium Notes (section)

==Old Earth and the Sol System in general==

In general, non-humans aren't allowed to set foot on Earth past the Daisy Chain without the proper permits. Old Earth being restricted to humans is more a matter of privacy than anything else. Old Earth is a pretty big deal to humans and holds a lot of spiritual significance, regardless of religion, and they don't want a veritable horde of xeno tourists coming in and messing everything up like drunks spray-painting a holy site. However, the Imperium also tries to afford the same kind of respect to other species. Xenos generally aren't allowed outside the Xenos districts of Craftworlds without prior permission, non-Tau are generally not allowed on T'au, etc. Exceptions are generally made in the case of emergencies like a ship being blown off course because of a warp storm.

That said, Old Earth does have non-humans on it, just not very many. Annual permits are issued for non-humans to visit Earth. As is the case for some places today, foreigners (by which I mean non-humans) can rent places, but they can't buy property (then again, few can buy property on Old Earth). Ambassadors from the Craftworlds and non-human civilizations get a pass, as well as seers and other people who work for the Administratum. You get tourists and students who are able to articulate well enough that they won't go getting drunk and disrupting cultural sites. Merchants and traders who want to sell wares (though it's generally a bad idea trying to sell tech in Mars' backyard). And of course Isha and the Handmaidens get a free pass because it would be stupid for the fricking Empress to not be allowed to set foot on the throne world.

On the other hand, most foreigners and tourists don't even care if they get to set foot on Old Earth specifically. Urban sprawl has reached the point that the entire Sol System is considered the metropolitan heart of the Imperium, to the point that most visitors from out-of-system (human and otherwise) usually end up touring around the outer parts of the Sol System and still feel like they can say they've visited the Imperium's capital.
