- "Because if you don't cooperate... I'll open The Door."
- -The Landlord
The Door is the incentive the Landlord uses to keep the Final Fantasy villains in line. The Door itself has not been seen as of yet, and its undoubtedly horrific contents have yet to be revealed to the reader. So far, only Mateus and Sephiroth have attempted to rebel against the Landlord, and when they did, they were told the secrets of The Door. They now serve the Landlord without question.
Though the Door was the original idea of the Landlord, it was The Creator who provided the horrific thing for him.
