Ghastly Manor is my version of Disney's Haunted Mansion Story
In the 1940's, a man named Henry Ravenswood found Legends Park, a town located in a supernatural bamboo forest. With his wealth from America, Henry commissioned a large Gothic Revival/Renaissance Revival/Mayan Revival manor to be built for him on the hillside overlooking the town and the mountain which he his wife Martha and their daughter Mélanie Ravenswood would all live in. Being an overprotective father, Henry refused to let Melanie leave the estate for her entire childhood causing her only friends to be the siblings Anna and Jasper Jones, Jasper having been Henry's faithful manservant, and Anna having been the mansion's chambermaid who was secretly being pressured into an affair with Henry.
As a young woman, Melanie was allowed to journey outside of the house's grounds where she met a line-foreman working for the Big Thunder Mining Co. named Jake. Melanie and Jake fell in love and planned on getting married however Henry was strongly against the union due to Jake's social class, and how Jake wanted to take Melanie away from Legends Park, so Henry refused to allow the two to wed.
One year later, a great and terrible earthquake hit the town of Legend Park while Henry and his wife were out in the town. The earthquake sunk a large portion of the town into a canyon in the town, effectively killing everyone in that portion of Legends Park, including Henry Ravenswood's wife Martha. The great tragedy's origins were unknown with it being rumoured to have been the work of the Thunderbird enraged by the mining town, or the result of a large explosion from a mining accident located deep underneath Big Thunder Mountain. Either way the town was left in ruin and shock, the sunken portion of Legends became known as Legend Canyon and became rumoured to be haunted by the victims of the earthquake. In order to properly mourn those lost in the disaster, Melanie had a small cemetery called Ravenswood Graveyard built on the Ravenswood estate for her Mother to be buried in.
Henry did everything he could to stop the wedding, but his useless attempts were put to a stop when he found himself lured into a secret chamber in the Manor where he was attacked by a wedding guest named Master Edgar Gracey who tied a noose around his head and hanged him to death in the Manor's cupola. Melanie was left the orphaned heiress to the Ravenswood fortune and household, leaving her nearly completely alone with no-one but the Jones siblings and her beloved Jake.
With her parents dead, Melanie decided that she wanted to marry her beloved Jake and they planned to wed in the Great Hall of Ravenswood Manor with a large assortment of guests. While still in the process of getting ready for the ceremony, Jake found himself and Melanie visited by Herny's ghost, who introduced himself as the "Ravenswood Phantom". Weeping at the fact that he's been killed, he invited his dead, demonic friends from the afterlife to fill the house in an eternal party. A dark curse fell upon the house, and the shape of the house was slowly transformed by the evil forces. No one ever set foot in the house ever since.
Over the decades following the fate of the Ravenswood family, Ravenswood Manor became unofficially known as "Ghastly Manor" and became notorious as being a Haunted Mansion where supernatural occurrences would be seen and people would disappear. One notable disappearance was that of a criminal named Milo "One Eye" Jones who robbed the Legends Park Bank and was suspected to have hid out in the abandoned manor only to never be seen again. Around the years people form teams in order to investigate a large number of mysterious disappearances of people who journeyed into Ghastly Manor or merely the Ravenswood Graveyard.
