The new build is exciting! I have been thinking about Pyr.
First, I think Pyr is not Neru. Pyr seems to hold hatred towards Neru and mostly uses a mocking tone. When Neru asks Pyr who he is, Pyr already knows Neru would not recognize him and Pyr says it is ‘heartbreaking’. Therefore I think it is likely that Pyr is Obli.
Second, at the end of Ch 1 and the start of Ch 2, we know the burned man is not alone in Record Storage. Since the burned man is watching the records (Prologue and Ch 1) and Prologue ended abruptly because the playback was ‘interrupted’, it is reasonable to guess Pyr is with the burned man in Record Storage. Speaking of the Carcass, the time egg says it ‘is a facility counting with the latest advancements in soul technology and magic’. The Carcass should be closely connected with the descendants or the shapeshifters. I am not sure if the Carcass is the red mansion that Nomino mentioned due to the colour of the sky. (The burned man says the colour is black but Nomino said the colour was blue. Or we just need to for a while for the sky to turn blue, or the sky was once blue but then turned black, if the Carcass is indeed the red mansion. Could it be the single record that is below even Shax and Nerus’ story?)
We know Neru is in the void (or once was), and he ‘transformed into something he never meant to be’. At the end of Prologue, the playback is severely interrupted by Pyr, who never show up again in Ch 2 (upon Build 0.6). Pyr asks the burned man to end ‘this endless tale’ with him (though the burned man has seemingly forgotten about the Backlog). I think ‘endless’ means ‘repeating’. There are branching timelines with some common events in the time egg and Obli in Ch 2 asks himself if there are other ways to handle the Battle of Aeon. I guess when the world is almost destroyed, God will show and rewind the clock, and the mission of the burned man is to help Pyr /Obli/Shax make the correct choice/change to end ‘this endless tale’. Neru or others related to Neru (like Alessia’s father?) should be suitable to play the role as the burned man.
Anyway, I think Pyr will show up (like at the end of Ch 2 or the start of Ch 3) because he just can’t always stay at the Backlog. Pyr is probably waiting the burned man reads the records and gains his memories. I notice that Prologue is noted with ‘the first and the last move’, I wonder if we will revisit the chapter to end the tale because it is where the ‘endless’ tale begins (if we temporarily ignore the record below Shax and Nerus’ story).
