Gabriel Knight: Sins of the Fathers

=== Setting ===
Sins of the Fathers takes place within a world where the occult and the supernatural exist throughout human history – such as ghosts, cultists and demons. To combat those who use such forces for evil against humanity are the "Schattenjägers" – a German translation of the words "Shadow Hunters" – who take it upon themselves to defend the innocent from such beings; their origins, however, are shrouded in mystery. The game's plot is heavily influenced by the history, background and mythology of voodoo – both the Americanized version found in Louisiana, and the West African version – mixing real-life elements of the practice with a number of fictionalized versions central to the story. The game mostly takes place across the city of New Orleans, but also features events within Germany in the fictional town of Rittersburg, and within Benin.

Characters

Players assume the role of Gabriel Knight, the protagonists of the story, voiced by Tim Curry, who investigates the murders plaguing New Orleans, with help from his assistant Grace Nakimura (voiced by Leah Remini) and police detective Frank Mosely (voiced by Mark Hamill). Other main characters in the story include: Wolfgang Ritter, voiced by Efrem Zimbalist, Jr.; Dr. John, voiced by Michael Dorn; Grandma Knight and Tetelo, both voiced by Linda Gary; and Malia Gedde, voiced by Leilani Jones. At times, the game features narration of certain events or examination of items by Gabriel, with these voiced by Virginia Capers.

Plot

Gabriel Knight, a struggling horror novelist who owns a book store in New Orleans, is compelled by strange nightmares to investigate a spate of killings across the city, dubbed the "Voodoo Murders", that could provide him material for a new novel. Although the police investigation into the murders led by Detective Frank Mosely, Gabriel's childhood friend, discount the voodoo elements behind the killings as unrelated, Gabriel becomes convinced they are genuine, and seeks information on voodoo from two experts: Dr. John, a curator of a voodoo museum; and Professor Hartridge, a university researcher who specializes in voodoo practice. Mosely later closes the investigation down, but not before a suspect he questions dies mysteriously following their interview, and Hartridge is murdered after discovering a link between one killing and a murder in 1810 that involved voodoo markings.
At the same time, his shop assistant Grace Nakimura, who aids him with research, fields calls for Gabriel from a man named Wolfgang Ritter, who claims to be family. Seeking answers, he visits his grandmother and learns from her that his grandfather, Harrison Knight, was a German immigrant called Heinz Ritter, revealing Wolfgang to be Gabriel's great-uncle. Contacting him, Gabriel refuses an invitation to see him at Ritter's ancestral home of Schloss Ritter in Germany to meet him, but agrees to accept a family journal from him. When he reads it, he discovers an entry concerning his ancestor Gunter Ritter, who executed a voodoo practitioner named Tetelo, after she betrayed his love for her by stealing a family talisman and using it to commit several murders. Gabriel finds these killings are identical to those of the Voodoo Murders.
Gabriel soon finds evidence that links John to the killings, but his friend Mosely disappears shortly after agreeing to re-open the case. Discovering that John is a member of a voodoo cartel in New Orleans, he decides to infiltrate the group at their next meeting. He is shocked to discover the cartel is led by Malia Gedde, a mysterious socialite whom Gabriel became infatuated with upon meeting, and to find she is possessed by the spirit of Tetelo, who recognizes him as Gunter's descendant. After narrowly escaping death, with Grace's help, Gabriel decides to leave the city for his own safety and look into his family's background at Schloss Ritter. Once there, he meets his great-uncle's assistant, Gerde, who reveals Wolfgang left before he arrived after determining where the family's missing talisman was taken to.
During his time at Schloss Ritter, Gabriel discovers that the Ritters worked throughout history as "Schattenjägers", combatting supernatural forces that threatened the innocent. Seeking to track down his great-uncle, Gabriel undertakes an initiation ritual, earning a key to the Ritter's private library. Through Wolfgang's notes, he learns the missing talisman was buried with Tetelo's remains in Africa. With this information, Gabriel travels to a burial mound in Benin, where he finally meets up with his great-uncle. Discovering he is now too weak to continue working as a Schattenjäger, Wolfgang instructs Gabriel to continue what he started and stop Tetelo, before sacrificing himself so he can reclaim the family's talisman. After sending his great-uncle's body back to Germany for burial, Gabriel returns to New Orleans, finding the city has descended into chaos in the last few days.
Gabriel finds Grace missing upon his return to the book store, with a note from Malia pleading him to flee the city. Reuniting with Mosely, who had gone into hiding, the pair infiltrate the voodoo cartel's hideout under the French Quarter, and rescue Grace. While she and Mosely escape, Gabriel confronts the possessed Malia, who slips into a fissure and clings to its edge. If the player chooses to kill Malia, she feels betrayed by him and pulls Gabriel into the fissure, killing them both, with Mosely and Grace mourning his death. If the player chooses to save her (considered the canonical option in the series), Malia realizes he loves her still and that Tetelo is too dangerous, and so chooses to kill herself, leaving Gabriel to discuss the outcome with Grace while reflecting on the new life he now has before him as a Schattenjäger.
