Poshley Sanctum
Located in Poshley Heights, the Poshley Sanctum (Japanese ピカリーしんでん Pikarī Shinden) is Pennington's home in Paper Mario: The Thousand-Year Door. This is where the Garnet Star is located, as well as the L Emblem which changes Mario's clothes into Luigi's. The room can be navigated by Spin Jumping off the star tiles on the floor to grab the various poles near the ceiling. Drop off the poles onto the ledges on the walls. Some of the ledges have Airplane Mode platforms to reach the ledges on the other side of the room.
At the entrance, when Mario first walks in, the Shadow Sirens and Doopliss can be seen with the fake Garnet Star. The break a window a get away, thinking they have the real Crystal Star. To keep the actual star safe, it was hidden inside the back walls painting. A hidden pipe behind a curtain transports Mario inside it. The painting shows a pipe outside the front entrance of the Sanctum. When Mario goes through the pipe into the painting, and walks inside the Sanctum, he'll be in the room of the real Garnet Star. This new area inside the painting is almost exactly the same, except it has different lighting and filled with Dark Boos. There's a pipe into this back rooms painting.
The first room contains a ! Switch to make the pipe appear to the painting. The back room has the L Emblem badge. Both need to be reached by using the poles near the roof to shimmy onto the wall ledges.
