Volume 1: the very ancient Republic
PAGE 3:
The
Moons of Jonsior are new. Clearly they are somewhere in the vicinity of Kaikielius, Ruan, and Foerost, so either in the Deep Core or on the border of it. (My own theory is that it was a gas giant, thus explaining why only its moons were colonized, but obviously that's neither here nor there.)
The stuff about
Kirrek and the
Great Hyperspace War are from
Tales of the Jedi: Golden Age of the Sith and
The Fall of the Sith Empire.
"Block-busting" Neimoidian developers moved in
See

PAGE 4:
Trantor pigeons are from
Yoda: Dark Rendezvous (they seem to now live on both Coruscant and Trantor).
Trantor was originally mentioned in the
Adventure Journal and is a reference to the city-planet in Asimov's
Foundation series.
Bal'demnic: WTS reference #1. You could make a pretty wicked drinking game out of spotting the WTS nods in this thing.
The "Givin mathematical theocracy" is from originally WEG (I think), but the specific phrasing of
devout Givin theoreticians is a sideways reference to jSarek's
Slyther Bushforb WTS entry. (Already time for shot #2, if you're playing along at home.

)
PAGE 5:
This section is largely new and fairly self-explanatory.
Vandar Tokare is from
KOTOR. The
Odominic kajidic is new. And no, it's not a Tuckerization of "Dominic," just a phonetic coincidence. Most of the interesting stuff here is going on in the epigraph.
Master Simikarty is from Zahn's
Outbound Flight novel, which established that he was the one who came up with the "only train kids" thing.
An
apologia is a self-justification or defense of a position. The term is from Greek ( απολογία ), suggesting in particular
Plato's Apology, and here I used it deliberately to give an "ancient" flavor.
habits that cannot be unlearned--passion, avarice, vanity, and all the rest. All of these, of course, are well-established as flaws for Jedi to avoid, but the latter two are also from the Catholic Church's list of Seven Deadly Sins. Zahn noted that by the prequel era, Simikarty's writings had been accepted as Jedi canon and held on par with the Code itself, so the vocabulary is meant to subtly suggest the reverential and quasi-religious place he later occupied.
Finally, the
Teyan Praxeum, on Teya IV, is from the SWAJ story
The Most Dangerous Foe. The exact connection is not spelled out; perhaps Simikarty wrote the influential apologias here. Since the Praxeum was founded 4,596 BBY the implication would be that Simikarty lived after that but before the reorganizations that occurred sometime after
TOTJ/KOTOR.
PAGE 6:
Billions and Billions is a reference to Carl Sagan's
famously misattributed phrase.
Tash Metonae is a reference to The2ndQuest's
Corla Metonae and
Galaxy of Fear's Tash Arranda, as well as DarthNTM's
Tash Scrambas (although he used the name for a dude).
With Jedi help, Kaikielius was made better than before, but its most notable features had been leveled during the pirate occupation and the Reconquista. If Coruscant was the galaxy's urban center, the reimagined Kaikielius was a cookie-cutter suburb. Thus explaining why a formerly-important Core World is rarely mentioned in existing books: it was no longer historically relevant and not much happened there anymore.
Yet due to its location it was a target of opportunity for would-be conquerors of Coruscant from Exar Kun to the resurgent Sith Emperor to Kaan to General Grievous. Respectively,
Tales of the Jedi: The Sith War,
The Old Republic MMO,
The Essential Chronology/Jedi vs. Sith/et al, and
Clone Wars. Note this is actually the first IU reference to
the Sith Emperor--the MMO publicity came out just in time for me to namedrop him and thus appear ahead of the game.
The idea of a Republic
aurodium standard is new but a reference to the real-life
gold standard.
Chancellor Vaila Pecivas is from a 2002
HoloNet News article. We know that he, Metonae, and Jideon Praji lived sometime between 1000 BBY and the start of the next section at 60 BBY, but I didn't feel the need to nail it down and risk hindering future story possibilities.
The stuff about
Phelarion and Lady Tarkin is from the very old newspaper strip
Princess Leia, Imperial Servant (now also archived as a
webstrip on Hyperspace).
One of
The Essential Guides to Characters (either old or new edition, not sure) established that
Lady Tarkin is a Motti.
Lithio Motti and the connection with the Prajii is, of course, new.
Lady Tarkin's first name,
Thalassa, is new. I get the feeling this will be what's remembered in five or ten years, after the rest of the article has been left by the wayside of continuity. Still, it's not a bad mark to have made.

"Thalassa" is a Greek sea goddess personifying the Mediterranean Sea, as well as a moon of Neptune, but there's no particular thematic significance--it just sounded cool and Star-Warsy.
The Bank of the Core Plaza is from
Republic Commando: Triple Zero. The
Financial District is from
Inside the Worlds of Attack of the Clones. And no, I don't know how this fits with the existing maps; that's why I merely said the Praji Estate was "near" the BOTC Plaza.
