I have indubitably done a post on this before , but I have this jolt of inspiration that I will write out right now
(so a lot of "campaigns" often last 3 sessions, so why not frame them that way)
1. THE EXPLODED SCHOOL:
A school of sorcerers had a sinister engine explode ripping apart the school. BUT a magic protection has frozen time mid explosion and the players are students who must escape the school with its now mid-explosion configuration . Also the outside world hates the wizzys and the players would best use this opportunity to "obtain" as much of the schools artefacts to allow them to survive in the outside world. The time stop magic is inconsistent and certain previous contained hauntings and elder beasts now wander its weird halls. Further CONFOUNDING YOU are the hounds between time and other inter-spatial blights coming it through the cracks
2. GHOST TRAP HOUSE:
basically the plot of 13 ghosts except with more ghosts, robbery, and murderous machinations.
An unrated movie by the way!Here's a link to the synopsis
if you haven't seen it and just want to know right now
Just like the movie! Except the iceberg broke off a chunk inside the ship and protein starved tardigrade people defrosted and are running amok eating people! And the players are the under class forced to work in dangerous conditions below, because rich people have their souls kept in jars above! And some asshole thought it would be a good idea to have a monster zoo onboard!
the players are planning the ultimate heist! Getting all the balls, kites, and dogs that the scary old lady next door to the park claims when they go onto her property. Her property is a vast overgrown thorny mess and her house a crooked 3 story dwelling, squatting there like a underfeed toad.
5.SNEAKING OUT OF HELL
Like Dante's Inferno but in reverse and more like Aristophanes's The Frogs
6. GALLERY OF THE DAMNED
You are vice sodden dilettante,ingénue and fops invited to a private viewing of a renowned (and infamous!) art patrons gallery. But once gathered around his sinister collection he reveals himself to be the very Devil! You are cast into a painting and must struggle through the weird worlds depicted, as you leap from painting to painting, each one twisted to reflected the various sins and betrays that have made up your characters degenerate existence (ala silent hill)
