The Horror has arrived

This is a cosmic horror campaign set on real-world Earth in 1912, beginning just after the sinking of the RMS Titanic in April. The world is historically accurate in technology (early automobiles, telegraphs, wireless radio, dreadnought battleships, no airplanes in common use yet) with low magic — but what appears as "magic" is actually forbidden eldritch knowledge from alien entities, driving practitioners to madness. The unique element is a sudden, ongoing invasion by horrifying extraterrestrial beings from beyond the stars, Lovecraftian horrors that defy comprehension. These aliens arrived via meteor-like fragments crashing worldwide starting in late 1911/early 1912, coinciding with global tensions. Humanity's arrogance in the Edwardian era crumbles as insignificant mortals confront the vast, indifferent cosmos. Survival demands silence on land, avoidance of the seas, and resistance to mind-shattering truths. The tone is one of existential dread: guns and armies are futile against these abominations, and knowledge itself is a curse.

The world mirrors real 1912 Earth: major powers include the British Empire (dominant navy, colonies worldwide), German Empire (rising military power), United States (emerging industrial giant), French Third Republic, Russian Empire, Austro-Hungarian Empire, and Ottoman Empire. Key cities: London, New York, Paris, Berlin, St. Petersburg, Tokyo (after Meiji Restoration). Geographic features remain the same, but now twisted by invasion — oceans are death zones patrolled by the Leviathan and its spawn; coastal cities like New York and London are besieged or abandoned; rural lands are hunted by silent predators. Inland empires (e.g., Russia, central Europe) fare slightly better initially, but meteor crashes have scarred landscapes with unnatural craters emitting maddening whispers. Trade routes collapse as ships vanish.

Primarily humans of 1912 ethnicities and cultures: Europeans (British class system, German militarism), Americans (industrial optimism shattered), Asians (Japanese modernization, Chinese republican upheaval post-1911 revolution), Africans and colonized peoples (under imperial rule). No fantasy races — all human, emphasizing cosmic insignificance. Relationships strained by war preparations (Balkan tensions brewing) now overshadowed by alien threat. Some cultures interpret invaders as divine punishment or ancient gods awakening (e.g., linking to mythologies).

The primary threat is the alien invasion: meteor fragments rained down starting months ago, unleashing horrors. Political tensions (e.g., impending World War I alliances) persist but are secondary — nations initially blame each other for "secret weapons" before realizing the extraterrestrial truth. Opportunities for adventure: scavenging silent cities, investigating crash sites, fleeing coastal invasions, or uncovering cults worshiping the entities as new gods. Human vs. human conflicts arise over resources in a collapsing society.

"Magic" is rare, dangerous eldritch lore gleaned from alien artifacts or visions — spells cause sanity loss (use D&D sanity mechanics or Call of Cthulhu-inspired insanity). No benevolent deities; traditional religions (Christianity dominant in West, etc.) falter as priests witness horrors and question faith. Some turn to desperate cults worshiping the invaders (e.g., "The Whisperers" who believe submission brings mercy). True "gods" are the distant Outer Entities — incomprehensible, uncaring forces that birthed the invaders.

The material world has been breached by "folds" in reality from the Outer Void — a non-Euclidean dimension of madness. Meteors tore these rifts, allowing entities to enter. No easy travel to other planes; exposure warps reality locally (e.g., angles that don't add up, impossible geometries at crash sites). Prolonged contact risks pulling in more horrors or driving areas into perpetual nightmare.

Pre-invasion: Mirrors real history — Industrial Revolution, imperialism, scientific progress (e.g., radioactivity discovered recently). Ancient legacies: Ruins or forbidden texts hint at prior "visitations" (e.g., misinterpreted myths like deep-sea gods or biblical Leviathan). The invasion era begins 1912, marking the end of human dominance.

Pre-invasion: Gold standard, booming trade via steamships, early stock markets. Now collapsing — oceanic trade halts (ships devoured), currencies worthless in chaos. Barter emerges; scavenged goods, ammunition, silent tools valuable. Coastal economies destroyed; inland trade routes overcrowded with refugees.

Justice breaks down rapidly — martial law in surviving areas, but enforcement impossible against aliens. Societies view adventurers as desperate survivors or madmen: useful for scouting dangers but suspected of cult ties if they know too much. Class divides persist initially (rich flee inland first) but erode in survival struggle. Silence becomes law on land; noise means death.

The invaders are utterly terrifying Lovecraftian aliens, emphasizing cosmic horror over gore. Land: The Silencers (inspired by A Quiet Place creatures) Blind, armored extraterrestrials with hyper-acute hearing. They hunt any sound, bursting forth with impossible speed to eviscerate prey. Bulletproof plating opens only to expose sensitive inner ears — vulnerable to high frequencies (e.g., improvised from early radios or whistles). Societies enforce absolute silence: sign language, bare feet on sand paths, muffled everything. A dropped tool or cry spells doom. Mere sight induces unease; their alien physiology defies biology. Ocean: The Leviathan A singular, colossal entity — miles-long serpentine abomination with tentacles, eyes that induce madness, and a form shifting between whale-like bulk and impossible angles. It devours ships whole, boiling seas in its wake. Spawn (smaller deep ones or shoggoth-like protoplasm) infest coasts. Oceans are forbidden; survivors whisper it as the "Awakened Depth," a Great Old One stirring from eons-long slumber, triggered by the invasion. Other Creatures: * Star-Spawn: Massive, tentacled behemoths at crash sites, warping reality. * Mi-Go-like Horrors: Fungal-crab entities abducting humans for experiments. * Deep Ones Hybrids: Emerging in ports, infiltrating as "changed" survivors. * Dimensional Shamblers: Invisible stalkers pulling victims into voids. Cults: Human collaborators driven insane, performing rituals to summon more.
