Connecting Armstrong's 15 characters
Separating by species, Armstrong played 4 Klingons, 3 Cardassians, 3 Humans, and 1 each of Romulan (R'Mor), Species 571 (Lansor), Vidiian (Drenol), Hirogen, and Kreetassan.
The four Klingons (Korris, Korath, Korbus, and the Unnamed Somraw Captain), might all be members of the House of Korath, formerly the House of Monak in Beta Canon. In a bit of name-recycling, I like to refer to the Somraw Captain from Sleeping Dogs as "Monak" and assume he's a grandfather or great-grandfather of Korath. Korris and Korbus (all interestingly named "Kor*", perhaps in honor of Kor?) might be close kinsmen, perhaps even a set of triplets.
The three Cardassians (Danar, Seskal, and the Unnamed Karoon Gul) might be similarly related. It could even be that Seskal and Danar are the same person, using an alias or just different parts of his name (Gul Seskal Danar?). The Karoon Gul is not Seskal and probably not Danar, because he was active after Seskal's onscreen death and of a different personality than Danar (although he was certainly undercover, per hints in the game).
The three humans are actually two humans (Fairbanks and Forrest) because of the mirror universe Forrest in the list. Admiral Fairbanks is a late 23rd century officer who might be a grandson of Admiral Forrest via Shannon Janeway rules.
