Le Serpent Rouge puzzle is a puzzle found in the video game Gabriel Knight 3: Blood of the Sacred, Blood of the Damned. It is a puzzle which surrounds a document of the same name, where protagonist Grace Nakimura attempts decipher riddles found in 13 different passages of the document. The puzzle was created by Jane Jensen, who also designed the game, and was inspired by the real-world poem of the same name, although she modified parts of it to make it solvable for players. Jensen was inspired in part by the works of author David Wood as well as the book "The Tomb of God". The new fully controllable 3D camera was also a factor that went into the puzzle's design. The puzzle has received generally positive reception, with adventure game fans regarding it as one of the best puzzles ever made. Critics from Adventure Gamers identified it as a highlight of Gabriel Knight 3, while Just Adventure and Adventure Gamers considered it one of the best of all time, the latter offering particular praise to the execution of its "over-arching nature". Puzzle and solution The Le Serpent Rouge puzzle is present in the video game Gabriel Knight 3: Blood of the Sacred, Blood of the Damned. It refers to a document found in the game, containing hints as to how to find the treasure of Rennes-le-Chateau. The document contains 14 segments: 13 that take from the zodiac symbols, and one extra. One of the game's characters, Grace Nakimura, first learns of the document from a conversation with two others, Estelle Stiles and Lily Howard. Nakimura is told at different times that the document was either deposited at the French national library and has since gone missing, or that it never existed in the first place. She later discovers an envelope taped to a museum door, which turns out to contain the document. The document contains multiple riddles, and Nakimura is tasked with solving them. Each passage contains a poem, and each poem contains secrets in Saint-Sulpice. As Nakimura discovers more information, she finds more layers to the poems, which then reveals new images, text, and clues for players to utilize as part of the puzzle. Players use a computer designed by Nakimura called SIDNEY, which analyzes the diagrams and maps, translate text, and perform "cryptographic and anagrammatic" functions.
