Possibly this is already known, but...
In "Beyond the Cloudspine" We come across a stone idol that is a frankenstein Computer God. When the dwarf is moved close it remarks about how "they've" finally overthrown the "mad, deadly, wordwide, ganster, communist, frankenstein computer god."
This in-game joke appears to be based on the writings/rantings of Francis E. Dec (http://en.wikipedia.org/wiki/Francis_E._Dec).
On a related note, horses are seen in the journal accounts in myth 2, but are they seen or refered to in TFL? (If not, maybe the F.C.G were suppressing them!)
And finally, what if the idol/computer god is a godhead of the ghols? We know practically nothing about their god, and we see ghols near the idol in "Beyond the Cloudspine" A dwarf dialogue text mentions that they overthrew the godhead of the ghols at either Myrgard or Stoneheim, so what if they did so in multiple places at the end of the great war?
