The old Fletcher Manor was a place in Hillsbrad Foothills, that the party visited when Turuk Thunderhoof, Gan Jedi, and Drom Foebreaker were on a diplomatic mission in Lordaeron together with Servius Felheart.
The manor was the home of the Fletcher family, which at the time had two remaining heirs: Gideon Fletcher and Dareau Fletcher. Dareau lived at the manor together with his servant, Magnus, and had over the past while been sinking deeper and deeper into a strange madness that his brother Gideon sought out adventurers to try and break.
It turned out that Dareau had received a visitor from the Void, who had promised him great power -- and the return of his dead lover Jocelyne -- in return for Dareau luring travellers to their doom. Whenever someone would come knocking, he would offer them a place to stay for the night, and once they were settled in the minions of the visitor would overwhelm and abduct them.
Then The Adventuring Party investigated the manor at the request of Gideon, they too were attempted lured into the clutches of the visitor. However, they were able to overwhelm the visitor's thralls, put a stop to Dareau himself, and even take the battle to the visitor to break the link that allowed it to set foot in the phyiscal realm through the manor.
