"This is classified information!"

This article contains unmarked spoilers. You have been warned.

As Operation Aeneas, started in Fixed Point, unfolds, Statesec dispatches secret Doll agent Instructor Я under the name “Lyudmila Pavlichenko” to carry the asset codenamed “Grand Duke” to the Commander in Berlin. Lyudmila will travel undercover in the “Future” Intercontinental Railway, along with an eclectic cast of characters: the mysterious Doll Erma searching for her creator, the con artists Maggie and Catherine Ponzi, Ms. Valeriya and her retinue, the industrial droid Pavel and the strange Villanelle. The protagonists must not only face Paradeus, but also their own pasts to survive the trip.



The name of many chapters in this event are taken from pieces of classical music and opera:

  • The most plot-relevant reference is “25 Ruslan and Lyudmila”, an opera by Mikhail Glinka. It tells the rescue of princess Lyudmila by the knight Ruslan, a parallel to Instructor Я's code name Lyudmila Pavlichenko and her air support code named Ruslan. Other opera references include “3-γ1 Méditation from Thaïs”, titled after the piece “Méditation” from Jules Massenet's Thaïs, and “5-β7 Cavalleria Rusticana” by Pietro Mascagni.
  • “3-α1 Waltz in A minor”, “3-α3 Raindrop”, “14 Ballade in G minor”, “35-W4 Tristesse” and “35-N1 Fantaisie-Impromptu” reference pieces by Chopin.
  • “35-N2 Spring Sonata”, “5-α5 Moonlight Sonata”, “5-γ7 Choral Fantasy” and “9 Ghost” are pieces by Beethoven. “3-β3 Symphony No. 3”, “5-β6 Symphony No. 9” and “30 Symphony No. 6” are also symphonies most commonly associated with Beethoven.
  • “3-α4 Little Prelude in G minor”, “3-γ4 The Well-Tempered Clavier”, “13 Goldberg Variations”, “35-T2 Prelude No. 5” and “35-R4 Piano Concerto in F minor” are by Bach.
  • “5-β4 Introduction and Rondo Capriccioso”, “5-β5 Danse Macabre” and “18 The Swan” are by Camille Saint-Saëns.
  • “5-γ5 The Canary” and “32 1812 Overture” are by Tchaikovsky. Fittingly for the final battle map of the event, the 1812 Overture famously includes cannon shots as instruments.
  • “5-α7 Winter”, “10 L’estro Armonico” and “29 Summer” are from Vivaldi.
  • “35-W2 Clarinet Concerto in A Major” and “35-P1 Twelve Variations on “Ah vous dirai-je, Maman”” are by Mozart.
  • “12 Gnossienne No. 1” and “35-C1 Gymnopedie” are by Erik Satie.
  • “35-R2 Sommeraften” and “35-W1 Solveig’s Song” are by Edvard Grieg.
  • “8 Rhapsody on a Theme of Paganini” is by Rachmaninoff and “35-P2 Death and the Maiden” by Schubert. “35-T4 Moments Musicaux” could refer to a piece of either artist.
  • Other referenced classical artists are Schumann with “3-β2 Symphony No. 2 in C Major”, Stravinsky with “5-β8 The Firebird”, Handel with “16 Concerto Grosso in A minor”, Brahms with “17 Brahms Intermezzi”, Liszt with “21 La Campanella”, Mussorgsky with “22 Night on Bald Mountain”, Strauss with “26 Thus Spoke Zarathustra”, Wagner with “27 Ride of the Valkyries”, Pablo de Sarasate with “31 Zigeunerweisen”, August Wilhelmj with “33 Air on the G string”, Debussy with “35-T3 Romance”, Ravel with “35-R1 Tzigane” and Edward Elgar with “35-P3 Salut d’Amour”. “35-R3 Piano Quintet in B minor” and ranking map “Todesfuge” could refer to multiple artists.
  • More contemporary pieces include “3-β1 Gene Takes a Drink” by Michael Gordon (related to “Gene's Bar” in the event's story), “3-γ3 Vladimir’s Blues” by Max Richter, “35-T1 Étude No. 2” by Philip Glass, “35-C2 Moon River” by Henry Mancini and Johnny Mercer and “35-C3 Starry Starry Night” by Don McLean.
  • “5-γ8 Torna a Surriento” and “35-C4 O Sole Mio” are examples of Neapolitan songs.
  • “3-γ2 Courante”, “5-α6 Chaconne”, “23 Con Espressione”, “35-N3 Minuet” and farming maps “Quartet Rondo” and “Quintet Rondo”, labeled Largo, Andante and Presto in Normal, Hard and Nightmare difficulties, use vocabulary from Renaissance and Baroque music. “5-α8 Stradivarius’ Magic” is named after the famous instruments of the Stradivari family. “35-W3 Tour di Mantova” references the Italian town of Mantua, important in the musical history of Renaissance.
  • “3-α2 Wind, Sand and Stars” is titled after a novel from Antoine de Saint-Exupéry. This is relevant to Longitudinal Strain because it is the novel on which Saint-Exupéry's later book Le Petit Prince was based, and this novel is tied to Pavel.
  • “36 Vox Lux” is Latin for “voice of light” or “voice of enlightenment”, as this final chapter reveals the true conclusion of the story.
