This office was once used by then-Defence Against the Dark Arts Professor Galatea Merrythought, but is now used by the Ancient Runes Professor. Fairly roomy, this office included a fireplace with two large sofas surrounding it, a round dinner table big enough to sit ten people and access to a private balcony. It had enough space to hold a Christmas party. Also, the room has two entrance doors, with at least one connecting to the sixth floor.
