Spoilers for 1.5 update , my speculation about new regions

So some thoughts on 3 brand new regions based on some details

1.>!Migration Path is although looking in lower sections like Subterranean, still has some additional architecture and geometry that doesn't make sense, also local pearl underlines other language naming system. So my theory it's either dried down seabed covered in sand (like aral sea) with close proximity to void sea due to darker atmosphere on lower levels. Or it could be so far into the future that dust covers the whole world and we have another civilization evolved (but why do they use the same medium for storing data like pearls(?)).!< 2.>!Pillar grove is located somewhere very close to local group due to local biome having dropwigs, rain deers in it's vicinity.It might have been an experimental facility based on that big white room with pearls (?).!< 3.>!Fractured gateways is definetly looking like Verdant waterways (name checks out). Probably algal blooms have corroded pump system to the point of breaking, making biome much drier which attributed to airborne algae to die off and introduce stagnant water conditions - ideal for locusts breeding. It also might be a thing that it was somewhere nearby Badlands and Transmission spires since we have two species (locusts and adapted kind of whale) in the he same area.!<
