I figured I'd start a discussion with, what I think, is one of the obvious locals Numenera could expand to--but that may not be discussed in detail in the core.
It stands to reason that at some point in the previous 'Eight Worlds' Mars was terraformed. I'm not sure if Monte already has plans for this but I thought it may make an interesting topic to talk about before we get more specifics about the setting detail in the core book(s).
Something I think could be very interesting is that mars offers a chance to have had, perhaps, hundreds of millions of years of development completely independent of the earth.
Here are some basic premises i've considered for mars:
It could be the case that the 'Third World' terraformed mars. A collapse occurs and both civilizations crumble. Mars independently has it's own rises and falls. Maybe in the 'Fifth World' era is the first time humanity makes it back to Mars. There is some cross pollination at this point again.
This could allow for mars to conceive of themselves as not originating from earth but still have legends and depending on how that contact goes, certain feelings about earth.
Maybe terraforming of mars was tried early on but mostly abandoned (given the idea of transdimensional rifts and such it is conceivable that it would be easier to simply use somewhere other than mars rather than putting effort into making it habitable)
Enough of the terraforming was begun that as the sun heats up mars becomes a viable life giving planet on it's own and the bits of life left behind evolve independent of earth.
This would allow for a pretty alien mars with little attachment to earth, and a pretty variable timeline to fit the type of mars you want into your own campain.
Mars is extremely closely tied to earth. In this concept there is an easily accessible gateway, or portal, leading right to mars. Mars is more like another contenant than something truly foreign. It's evolved mostly parallel to earth since whichever era this gateway(s) were stabilized.
All of these premises can be taken in many different ways. Maybe mars was a garbage dump which now holds treasures, maybe the civilization over there is highly organized and militaristic serving as a foreign force intent on concurring. Maybe it's a paradise with resources beyond that of earth.
Has this been talked about anywhere?
