Benny wants excitement, adventure and thrills, so she heads for the outer Rim. Clarence and a suddenly incredibly talented Jason want her not to have them, so they follow her in order to prevent any excitement, adventure and thrills coming her way. There's also a plot MacGuffin called Dorpfeld's Prism which makes you a strange combination of happy and stupid. And that's about it.
Jason Kane and Clarence.
Braxiatel and Chris Cwej (second body) make brief appearances.
Not much. It's all pretty self-explanatory and self-contained.
Pg 8 "But now that so many of her actual memories were gone, had been wiped away by the organic programming that had invaded her mind." Benny lost a chunk of her memories at the conclusion of Return to the Fractured Planet.
"She might as well be the ersatz version of herself that had been given life in the largely fictional and wholly melodramatic Adventures of the New Frontier." The in-universe, fictionalized and pulpy versions of the NAs, as first introduced in The Mary-Sue Extrusion.
"For several months Benny had actually been dying." Revealed in Tears of the Oracle and cured in Return to the Fractured Planet.
Pg 11 "Like the real Versailles had been. Maybe that was why the place seemed so familiar." It's actually familiar because she's been here in her personal past and the place's future in Theatre of War, but has clearly lost that part of her memory.
Pg 12 "The arches of the mirrored alcoves and the windows were ornamented with a round symbol, a disc filled with swirling embossed lines." Braxiatel has never decorated the Collection with the Seal of Rassilon, has he?
Pg 13 "Benny wondered whether [Cwej] found it easier to cope with his change of body than she found coming to terms with her change of mind." Chris regenerated in Tears of the Oracle as a result of radiation poisoning that he suffered in Dead Romance.
Pg 16 "We're your friends, after all. We're here to support you in whatever way we can, in whatever way you think best. That's what friends are for." Friendship was a very specific theme in Tears of the Oracle.
Pg 17 "And fat and balding wasn't on my list, I have to say." Chris is not entirely comfortable with his new regeneration, as made clear in Tears of the Oracle.
Pg 31 "What a tosser. Can't even write properly." Jason is critiquing the work of another author as he is now published in his own right as a best-selling author of interspecies porn, as made clear in Beige Planet Mars.
Pg 41 "Maybe he's read my book." Benny's sole published work, Down Among the Dead Men, was first mentioned in Theatre of War.
Pg 98 "Records are vague. The war, you know." The war with the Daleks which happened in the wake of Frontier in Space which is also an incredibly convenient excuse (in multiple books) as to why information on this or that particular plot MacGuffin is so very scarce.
Pg 104 "Jason paused for a moment as he drew back his arm. He took careful aim, then flung the egg-shaped stone in a high arc above the crowd in front [...] The stone caught the power-blader on the forehead as it arced down." Jason's sudden and extremely unlikely ability to do pretty much anything perfectly extends to being able to hit a target moving on powered roller-blades across a long distance over numerous other people's heads to perfection. Dr John Smith does something similar in the TV Human Nature.
Pg 110 "I am Professor Fred Bloggs from the Archaeology Department of St Oscar's University on Dellah. Until recently, that is." Jason's cunning disguise notes that Dellah is no longer the seat of St Oscar's in the wake of Where Angels Fear.
Pg 136 Proto-Moffattian wordplay has the key to the mystery of the Dorpfeld's Prism's location being discovered because the word 'your' sounds precisely like the word 'you're'.
Pg 153 "You should never trust anyone from Mawaii. The i's are too close together." This is just an appalling pun.
Pg 196 "I lost some of my memories." Again, Return to the Fractured Planet.
Pg 225 "I assume it has no effect on my biomechanical brain." Clarence's brain is actually that of murderous People Ship C-Mel, introduced in The Also People. Clarence has recently learned of at least the name of his old identity in Tears of the Oracle, if not his deeds.
Pg 238 "'Sorry,' said Clarence as he held Jason. 'We did good here, didn't we?' 'Oh yes,' Jason agreed. 'We did excellent.'" Bad grammar aside, this is a reworking of the last couple of lines of Remembrance of the Daleks.
Pg 239 "'Well,' Dent said, 'if you're not having fun, then stop doing it. That's what I always say.'" Whilst this is a reworking of a line from the final scene of Resurrection of the Daleks. Maybe Dent also has an Auntie Vanessa.
Pg 247 "'Myerson asked what it was. He thought Dorpfeld replied, "My prism."' Braxiatel reached out tentatively towards the relic. 'In fact, he said, "My prison."'" Another example the kind of wordplay that Moffat would go on to make so much of in his tenure as show-runner.
OLD FRIENDS AND OLD ENEMIES
NEW FRIENDS AND NEW ENEMIES
Dent Harper, an adventurer.
Linn Sekka, a thief and shopkeeper.
Dr Creer, a post-death brain surgeon.
Nikole Medak, Luggar and Powlo Vertutes, all of the Cartel.
In bit parts, we also have Squeezer Hedges, a mafiosa-esque boss; the manager of the Hotel Xcelsior; Heath Conley; and Gunzo Macklin.
The planet Virabilis in the Eastern Rim, including the hotel Xcelsior and a big white/not-white villa sitting on top of a waterfall.
Prevaria City is on the planet Prevaria, itself so close to Virabilis that atmosphere is shared between the two of them.
