Long before Dipper and Mabel's arrival in Gravity Falls, Archibald Corduroy was among the lumberfolk commissioned by Nathaniel Northwest to construct their grand manor using the illustrious fortune garnered from the Northwest Cover-up. Enticed with promises of a lavish party open to all of Gravity Falls' residents, Archibald and the lumberjacks worked tirelessly to complete the manse, and endured dozens of sacrifices from the harsh working conditions.
However, upon the construction's fruition, the Northwests reneged on their promise and denied the town's commoners entry to the festivities, enraging Archibald and the lumberfolk. Before his untimely death in the Great Flood that shortly followed, Corduroy cursed the entirety of the Northwest family, swearing to return and exact vengeance upon them should they still refuse the citizens of Gravity Falls admittance to the party.
In "Northwest Mansion Mystery," Pacifica Northwest discovers him in her family's home and contacts Dipper Pines to help her capture the specter. However, he soon overwhelms the children. Dipper consults his Journal for advice, but only finds a suggestion to "beg for mercy." However, Dipper manages to trap the ghost in a silver mirror.
The ghost tells Dipper his story, and attempts to convince the boy to release him. Dipper refuses, as his sister was in the manor, and he didn't want her to get hurt. The ghost then requests that Dipper let him see his beloved trees one last time. Dipper agrees, holding up the mirror. The ghost makes the mirror heat up, causing Dipper to drop it. The mirror shatters, and the ghost returns to the mansion, turning all the guests (and even Dipper) to wood.
Ultimately, Pacifica honors the deal made by her ancestors, opening the gates and letting the townsfolk in. The appeased ghost tells Pacifica that she is not like the other Northwests. He undoes his wood curse before finally passing on.
- 210. "Northwest Mansion Mystery"
"Come out... Come out... Wherever you are!"
"You've been had, boy. You remind me of me 150 years ago."
"150 years ago this day, the Northwests asked us lumber folk to to build them a mansion atop the hill. We were told it would be a service to the town, that once a year they'd throw a grand party, and all would share in the bounty. It took years of backbreaking labor and sacrifice, but when it was time for the grand party they promised the common folk of the town, they refused to let us in. With the trees gone the mudslides began. While they partied and laughed, I was swept away by the storm. And so I said with final breath: '150 years I'll return from death. And if the gates still closed to town, wealthy blood will stain the ground.' A curse passed down till this day."
"Generations locked away, my revenge shall have its day!"
"Yes, yes! It's happening. My heart, once as hard as oak, now grows soft like more of a birch or something."
- There is a picture inside Corduroy cabin of a man named Archibald Corduroy that looks identical to the ghost, prior to his death. This seems to imply that the ghost is an ancestor of Wendy Corduroy.
