Methane atmosphere on Maheo I (and maybe Niira) - surely an error?

[The Mustachioed Marxist]

Maheo I is home to a "Thin Methane" type atmosphere, temperate temperatures, weak magnetosphere, and marginal flora (fauna listed as marginal but with 0 species - microscopic life only?). Okay, seems reasonable.

It is also home to Sonny di Falco's Island compound. A (handcrafted and hand placed) mansion with an outdoor rooftop pool and bar exposed to the elements. On a planet with a methane atmosphere with 0% oxygen concentration. A planet where I will die within 30 seconds of removing my helmet. Not so reasonable. Surely some poor dev mistook a type "M" atmosphere as meaning the Star Trek type M, i.e. habitable, rather than the Starfield meaning of "methane" - right?


I considered that Niira might be in the same situation momentarily, because as far as I can gather from the lore, Niira was meant to be a habitable world before being decimated by the Colony War. Sure, the atmosphere is toxic, but would war really change it from an oxygen atmosphere suitable for humans to a methane atmosphere with 0% oxygen as well? However, I have found that the genetics of plant life on Niira is listed as being "methane based", and methane breathing animal life seems to be a thing in Starfield's universe based on other planets as well.

Still, it feels out of place for Niira to be an example of "garden world decimated by war" if the atmosphere was never breathable by humans to begin with, which must be the case since the apparently methane-breathing Sirens from the Colony War existed on Niira before the decimation and after.


Has anyone else encountered some seemingly out of place or incorrect atmospheres based on the life found there or the lore? In particular, non-procedural generation errors. I'm sure we've all seen heatleeches and xenogrubs on airless moons and the like.

I've also encountered animal life on a CO2 atmosphere world, also with 0% oxygen, but I'm not sure whether this is meant to be an example of alternate genetics and respiration mechanisms. (Serpentis III, I think).

Any animal life found on other atmospheres aside from Oxygen and Methane? What about Nitrogen atmospheres?
