Timeline of Endwalker Role Quests (Spoilers)

[Cleretic]

Not to mention, as 6.1 Role Quest shows, people are still at risks to transform into Blasphemies despite the requirements are much higher now. This may lead to certain Season 2 regions that are maybe Bloodborne like due to their inability to properly contain Blasphemies during the final days and after the final days.

To confirm, though, there's a difference between 'Blasphemies' and 'Terminus beasts'. The Blasphemy of the originator that can then turn others; the Terminus Beasts are the lowlier guys that turn after that. The rules are a little different in areas where the sky actually burns, but the Blasphemy's still the first person to turn.

My reading was that the Blasphemy in 6.1 was one that turned up during the events of the story, but we only found the thing later.
