Most of it's in the discovery and secret project blurbs.
I obviously embellished the story of Pria, but nothing I invented contradicts any part of the game.
Morgan lasts long enough to build a quantum power plant, so I goofed a wee bit thinking he doesn't survive to the end, and while I got Zakharov's reaction to the Lab Three incident right -- his reason for building the Voice of Planet seems to be fear of what he calls "an awakening God" -- he obviously researched the Green techs after finishing out the Singularity side or he wouldn't have been able to build the VoP. So I erred in thinking Deidre transcended while Zakharov was busy with Singularities -- Zak has both sides of the tree covered.
Zakharov is clearly ascendant in the end stages of the story. He builds both the Singularity Inductor and the Voice of Planet, meaning he researched both ends of the tech tree before anyone else -- particularly Deidre -- could skip the Singularity branch and get the jump on the Green techs. He may have stolen the high-end Green stuff from Deidre, but there is absolutely no doubt he has them soon enough to be the first to build the VoP.
The final blurb for Transcendence, spoken by Planet, is from Deidre's book, leading me to think Deidre actually builds the Ascent. It is almost unthinkable for the VoP builder not to be first to build A2T, though, as everybody builds A2T the turn after completing VoP. Zak wouldn't be dumb enough to delay, either, unless fear of Planet made him not want to Transcend.
Anyway, you get bits and pieces of the "real story" from the blurbs and you have to infer what happened from that.
