Mysterious Disk connected to Shadowlith?

[brobotics]

A thought I had, please disprove if the logs in Abyssal suggest otherwise:

Could the Mysterious Disk (theorized lost piece of Oculus or Godman super-alloy) be identical/related to the circular saw used to cut the Shadowlith open?

It's been a while since I read the logs down there next to the ACoNR, but I remember the circular saw tool they used had a heavy amount of secrecy associated with it. Notes in the delivery suggesting it was an artifact and they didn't want anyone knowing exactly where it came from or what it was. Also it would make sense that Godman tech is able to slice evil Leviathan shit.   

Does Eddy in Junkyard have a monolith to cut?

I think it's more likely that the Mystery comes from the disk having a quest cut, but this theory is cool too.

I think Disk could be a blueprint for a Mega Project,  the one that requires six Acorns.
