Editing The Machine (section)

===More on Engineers===
I see an underlying idea that is absolutely worth having: IE Engineers are only in an incredibly low activity state most of the time, but then at certain times they would all awake in a flurry of activity. These times are NOT regular, but can be predicted, IE following on the trope of having ancient diagrams from prior delvers, you could have one that requires a ton of decoding, and then by the time the party's number cruncher works through it turns out to be a prediction of the next engineer wake up call for that section is a minute or two away, followed by a FFFFFFUUUUUU- section in which everyone is desperately trying to escape.

Timing would be individual to segments so you wouldn't necessarily gain a lasting advantage from that. Civilisations could have sprung up in the sections that only receive maintenance every ~100 years or something, minor settlements in the ~10 year sections, but many segments would have a wake up call roughly every 5 minutes.

The idea of the Engineers being on a timer actually fits very well with a scenario I already had in mind.

After journeying through the alien Machine for days, encountering mechanisms they couldn't possibly begin to understand, the PCs come across what appears to be a fairly simple clock. Sure, it might not look like the ones they're used to, but it's definitely some kind of clock. But after inspecting it for a while, they realize it's counting down.

FFFFFFFFUUUUUUUUUUUUUUUUU
