One fun thing about reading way too many Star Wars novels is that you notice when authors make up something and then mention it in other books they write. I always go "That sounds familiar" and have to look it up, only to find out it's from a different book of theirs that I read.
So anyway, here are some Claudia Gray Specials from Into the Light:
Planets:
Pamarthe (and port-in-a-storm): First appeared in Bloodline because one of the main characters is from there, also showed up in Leia, Princess of Alderaan
Paucris Major: From Leia, Princess of Alderaan- the rebel fleet was being refurbished there
Zeitooine: First appeared in Lost Stars
Sibensko: From Bloodline, some big plot moments happen there. The first mentions of the Amaxine Warriors are also related to Sibensko!
Gatalenta: This hardly even feels like a Claudia Special but it is! First mentioned as the home of a main character from Bloodline, and then established as Amilyn Holdo's homeworld in Leia, Princess of Alderaan!
Other stuff:
Meryx gems: In Master & Apprentice, the requisite lovable rogues are jewel thieves who named their ship the Meryx because it is so valuable.
Muunyaks: Pack and wool animals that Ciena Ree's family owns in Lost Stars
Buttersweet Puffs: Given as a gift to Leia in Bloodline, and already established as something Affie Hollow loves
Toniray: This makes at least two drinks that Claudia has named that are served at Galaxy's Edge, and Toniray is in plenty of things that she didn't write, but it is largely in her books! And guess what, first mentioned in Bloodline.
And a little bonus, Czerka Corporation: Not really a Claudia Special, as it's from Legends, but she's the one who pulled it in for Master & Apprentice, where it is a major player!
