Come here... that is, if you still haven't given up.
The third in the series of Visual Novels including Sekien no Inganock, Shikkoku no Sharnoth takes place in an alternate reality Victorian Era London. Before the current young generation was born, England made contact with the advanced society known as Kadath and began trading Engine Machine technology. This technology has allowed England to become the dominant world superpower and appears to have allowed Queen Victoria to live years past when she would have died in our world.Our protagonist, Mary Clarissa Christie is currently attending university with her friends Charlotte Brontë and Angelica Derleth, happily spending their days as normal students. Only... Charlie has been a little off lately. When Mary tries to find out what is bothering her, she finds herself thrown into a dark version of London with no one in it. No one in it but her and the monster that wants to take her eye, that is. Eventually, she is saved by a strange man in black and swears a contract with him in order to return to her normal everyday life.Shikkoku no Sharnoth contains multiple references to Sekien no Inganock and is crammed full of figures from around the Victorian Era, whether they were alive then, or not. We're looking at you, Heinz Heger and Charlotte Brontë. And we're pointedly overlooking you, George Lestrade and Sherlock Holmes.
Tropes found in this visual novel:
All Crimes Are Equal: In Kadath territories, any law breaker is punished with death. No exceptions for the severity of the crime or the status of the one who committed it.
All Give and No Take – Howard gives and gives for Angie and expects nothing in return. He’s absolutely head over heels for her. She loves him back, but all gestures are definitely one sided.
Almost Dead Guy – Moran survives just long enough to tell Mary where Charlie is.
Ambiguously Evil – M. Never displays any sympathy and very rarely even any emotion, but he gets rid of the Metacreatures. Probably not doing it for the sake of mankind when considering he’s the only one with an actual Evil Laugh. Heinz and Moriarty qualify as well.
Arc Words – A few examples. 'Thus, I deny tomorrow,' a statement spoken by the screams that Mary finds. 'Have you given up yet?' asked by M and multiple characters (everyone that is not Mary, really) saying 'I have already given up.'
Anachronism Stew – In regards to the cast rather than styles or technology. Sherlock Holmes, Queen Victoria, Charlotte Brontë, Bram Stoker, Baron Munchhausen (though an obvious pseudonym, no one mentions it), Josef Čapek, Heinz Heger and more all at the same time. While many of them were certainly alive at the same time (and not being stuck to fiction) the ages don’t work at all and Heinz Heger and Charlotte Brontë were separated by over half a century.
Chick Magnet: Just about every woman who comes across M expresses some level of interest, ranging from intrigue to flat-out adoration apart from Mary and Charlie. Mary seems slightly repulsed, though interested and Charlie is mostly indifferent. And of course, Mary herself is sort of questionable given the ship tease.
Continuity Nod – Passing reference is made to Thoth, a character alluded to in Sekien No Inganock. Mary’s eye changing to gold is also very similar as what happened to Ati. David, a minor character, is referenced in passing.
Cool Big Sis – Charlie, normally. But she’s been a little off lately. Subverted near the end, and actually inverted when they were small children.
Delayed Reaction – Angie greets Viola Baskerville, an in-universe celebrity of sorts after the Hound of the Baskerville case, in an exceedingly friendly and familiar manner. Which is good, because Viola just wants to be friends. A few minutes later, Angie realizes who she’s been talking to, but subverts the expectation by continuing to treat her exactly the same.
The Ghost – Moriarty, Watson, Queen Victoria and Mycroft Holmes, though it is implied for some time that M is Moriarty. In the end, Moriarty turns out to be the old professor that people have been meeting in ways that break the stories' continuity.
Hitler's Time Travel Exemption Act – Heinz Heger is based on a real-life holocaust survivor. Given that the séance granted glimpses of the future and his later monologues, it appears he was trying to stop Hitler's rise to power.
Lotus-Eater Machine – M puts Mary into one after her sword fight. It appears to be based in part off the story she was writing, and things get disturbing around the point when she realizes what is going on. M interprets this as giving her a gift, but she doesn't want it.
Love Makes You Crazy – Čapek, Denny and Charlie. For Charlie, it's left open to interpret what kind of love it is, though.
Love Makes You Evil – Čapek and Denny/Churchill. Bram looks like he might qualify at first, but then it's revealed that it's not possible for the host to stop the Metacreature. He doesn't really want to chase Mary.
Jane for M in her backstory. She didn't really realize what kind of person he was and had a girlish devotion. M, for his part, simply didn't reject her being near him.
Moran for M. She unquestioningly obeys him, despite knowing he will never return her feelings.
Lovecraft Lite: The monsters are eldritch abominations, the supertech is actually supernatural and attracts said monsters as one of its unpleasant side-effects, and Lovecraft references abound including M being Outer God Nyarlathotep. But the situation gets resolved, humanity doesn't seem to be doomed to madness and death, and M is an Anti-Hero whose acts indirectly benefit humanity. Maybe.
MacGuffin – Mary's golden eye is apparently greatly desired by certain parties for reasons that are not initially clear. She is understandably reluctant to give it up.
Mad Love – M doesn't reciprocate the affections bestowed upon him, but he does not react or involve himself. He simply does not outright reject his suitors. Despite the clear lack of interest, multiple women are intensely devoted.
Magic Is a Monster Magnet – The use of Engine technology appears to cause magic mutations, which in turn attract Metacreatures.
Magitek – Engine technology, unknown to its users in London, is more than pure science.
Mismatched Eyes – Mary. And Charlie near the end, though her eye turns back to normal, unlike Mary.
My God, What Have I Done?: Upon finding out that whenever she helps M destroy a Metacreature, its human host is most likely killed too, Mary nearly suffers a Heroic BSOD. It's only thanks to Mary's determination to save Charlie that she doesn't.
Plucky Girl – Mary. Though she seems quite unwilling to involve herself in trouble, she's a much braver and willing to leap into action than she appears. The minigame is even based on keeping her mental strength high.
Science Destroys Magic - The dark kingdom disappeared as the light of human civilization grew. Its fantasy denizens eventually all left until only the king was left alone in his black, empty kingdom.
Sherlock Holmes – Holmes appears to be working against the vague Sharnoth plan. Numerous Holmes character can be seen or are mentioned, such as Moriarty, Moran, Lestrade, Mycroft and Watson. Arthur Conan Doyle, on the other hand, is something of a mad librarian.
Ship Tease – M and Mary, despite the fact that Mary fails to understand him and grows to loathe him as the story goes on. She chooses to save him in the end, but never appears to actually fall in love with him.
Unwitting Pawn – From the beginning, it’s clear that whatever Mary is doing is furthering the agenda of someone called Baron Munchhausen.
Verbal Tic – Moran confirms or denies information or inquiries with 'Yes. No.' or 'No. Yes.'
Victorian Britain – At least, it starts like that. And then Engine Machines show up, Sherlock Holmes wanders through and Winston Churchill introduces himself as an up and coming merchant. Although the time period is actually after the historical Victoria's death, she is still alive.
What Happened to the Mouse? - Several points lack proper resolution such as an explanation of Heinz, who Funnel is and more. The webnovel epilogue doesn't answer most of them either.
What Is This Thing You Call Love? – M is "interested" by Mary, but his emotions have burned out through isolation which makes everything kind of weird. The lotus eater machine scene he tries to give her as a gift of sorts is perhaps the worst part.
When She Smiles: Subverted. Moran smiles only twice, but at entirely inappropriate times, when she has sustained major injuries or is on the verge of death, and it doesn't comfort Mary at all.
Where the Hell Is Springfield? – Where is Kadath, anyway? It’s described as though it’s an alternate dimension with its own sky, but to get there you go north. If it was in the same world as Earth, then shouldn’t London have had gray skies for a much longer period?
Yandere: Charlie has a major fixation on Mary. She actually wished for Sharnoth to descend so that ‘tomorrow’ would never come and she would never have to be separated from her.
