Death may Die
At this point in the records at Kadeth, the depictions change noticeably. It looks as though the golden age myopia wears off from around 250 million years ago and a much more iron age motif reigns. Based on this and statements from SFS, it seems clear that at around this time the interplanetary Old One civilization collapses. SFS claims this was because of overspecialization in and over-reliance on biological science, causing the Old Ones to neglect other resources vital to interplanetary infrastructure.
The effect on Earth was to cut the Old Ones off from vital resources for sustaining their advanced civilization. Many of their tool organisms perish or become uncontrollable, and only a few remain. This causes an ecological collapse on Earth, one that eventually leads into the age of the dinosaurs. Earth’s dependence on foreign resource to sustain an unnatural ecology is quite clear – nearly 99% or all species go extinct on Earth without input from foreign resource.
The Old Ones themselves, over tens of millions of years, seem to have forgotten the details of their former glory, and believe in it as if it was a heroic age as compared to their modernity. Future behavior underscores this, but it overall also renders their depictions of things that aren’t known to us already a bit uncertain.
This Period demonstrates that the Earth still had dependence on the unnatural manipulations of the Old Ones, as at this point the remaining tool species of the Old Ones leaves their power. Some particularly unusual (and secretive) studies at Kadeth demonstrate the reason. Some or all of the tool organisms were designed to retain memory across generations – they were biologically simple in many regards, reproducing through parthenogenic fission.
Most likely, it was intended that periodically the industrial biocomputers, which were designed to formulate into shapes and capabilities for industrial purpose, would periodically be “wiped” of memory. Every learned reflex, essentially every command, started taking up space the thing didn’t have. Thanks to tens of millions of years of war and continual preparation for future war, these creatures had accumulated an enormous repertoire of reflexive behaviors.
At the start of the Triassic, the Old Ones lost control of their tool beasts. If there was more than one species of them before, they were left with a single species that they could tame. The species that didn’t get tamed were eradicated as much as possible. The Old Ones were of some aggression about it, but some evidence suggests the Great Race were the real aggressors, wiping out forests to kill the proverbial single dust mite. Global ecological collapse, the second in fifty million years, follows.
The Old Ones retain possession of a single species of tool beast, keeping it under control through some mechanism. SFS identifies it as “hypnogogic control,” whatever that means. It would seem that they used some form of hypnotic technique to much more precisely identify desired behaviors, to prevent confusion and violence.
Unfortunately for the Old Ones, the Triassic Period also brought a new enemy. In the last many millions of years, SFS had been rising up to fill the economic niche left vacant by the Old Ones. At this point they came to Earth, perhaps to harvest its ecological resources as the Old Ones did. However, the Old Ones fight them, just as they did the other functional excessions on the planet.
Unfortunately, the Old Ones had lost much of their former knowledge. Believing in the mythopoeic notions, it appears that they attempted to physically fly into space rather than use a vehicle (such as they did not at that time have). Determining it impossible to follow the SFS into space, they decided that they had degenerated somehow from the golden age. They managed to keep SFS off the planet, but couldn’t keep them out of the system.
According to SFS, they remained due to the wealth of a particularly rare resource found on Pluto or Charon, and established industrial sectors on those planets. The resources ran out, but the industrial system was still useful, so it became a place for industrial production.
Unfortunately, this didn’t prevent some serious attacks by SFS, and the initial attacks were catastrophic. After that, SFS continues harrowing and heckling the Old Ones, but they retain enough technical infrastructure to intercept SFS with some effectiveness as they enter the atmosphere. They also manage to find a way to intercept transatmospheric attacks (such as big, heavy rocks).
The SFS attacks dwindle over this time as the Old Ones fall back farther and farther. (Note: It isn’t clear what involvement or effect the Great Race had on the SFS or their war with the Old Ones.) Based on the pictorial evidence, it seems clear that by the dawn of the Late Cretaceous, the Old Ones no longer hold any land or sea holdings outside of Antarctica.
It’s possible the Great Race held more of the world, but if they were restricted to Australia (the only known place where they ever lived), then likely as not the SFS had rendered much of the planet hazardous to both of them, but couldn’t take action against the polar regions.
The best explanation is that SFS kept the Old Ones from holding any surface territory but their sacred realm of Kadeth, and the Raliites pushed them back from the seas. Eventually, the SFS and Raliite pressures combined to wither the former empire down to a single city overseeing a frozen landmass.
