Constellations lore book, entry “Severing”: [quote] The fall isn't quick. It happens over weeks and months: cataclysmic disasters, natural and unnatural, flattening human settlements on every planet || that I have made, I have shaped, my work, laid flat ||. Earthquakes. Tidal waves. Solar flares. Cyclones, sinkholes, exploding lakes, wildfires. Unknown, untreatable plagues raze populations in hours. Water goes black with unknown poisons || forced down my throat ||. The ground opens up and swallows entire cities || and I am sick sick sick ||.[/quote] Either this or something akin to this: Duress and Egress lore book, entry “Asher: Predictions”: [quote] It was late during what passed for night on Io, and while Asher was tired, he hiked on diligently. He stopped only once, briefly, to study [b]a snail whose shell was growing tiny clusters of crystalline black obelisks[/b].[/quote] I feel like the more likely option is the first one based on the fact that gambit and crucible maps on those locations are staying. This is also how the first collapse happened. However, total terraformation of the locations into deserts of crystalline and dark isn’t off the table.
