Palace of Shadow
The Palace of Shadow is the final area that Mario and his comrades visit in Paper Mario: The Thousand-Year Door, and is where the Shadow Queen resides. It is accessed by going through the Thousand-Year Door. The Palace is one quarter of the old city that was ruined 1000 years ago. Over the years during which the Queen reigned, the Palace became rich with stolen treasure, which became legendary over the centuries since her defeat.
In this palace, the Shadow Queen possesses Princess Peach, who Sir Grodus had delivered to her. Mario and company drudged through the palace and its inhabitants, including the middle sibling in the "tail" family, Gloomtail. Mario and his allies later fought with the Shadow Sirens, who now consisted of Beldam, Marilyn and Doopliss. Soon after, Mario's party finally made it to the Shadow Queen's inner sanctum, where Sir Grodus was. Mario and his party defeated him, and also defeated Bowser and Kammy Koopa, who literally "dropped in" on them unexpectedly. Sir Grodus retreats to the final room to use Princess Peach as an offering to the Shadow Queen.
The first room is rich and very detailed with roses and patterns. Past this is a bridge across an expanse of water, the cave "ceiling" can be seen here. The room afterwards is a large staircase that goes even farther underground. Later, a garden area shows off some streams and the Riddle Tower. After the tower's riddles are all completed, some ancient machinery will activate, causing the long hallway leading to Gloomtail to collapse, revealing a lower area filled with enemies. One of the last rooms is a huge chamber with odd pillars, and then, the throne room where Grodus uses Princess Peach. A secret door leads to a huge staircase down to the crypt containing the Shadow Queen.
The in-game map description reads, "The palace found behind the Thousand-Year Door in the ruins beneath Rogueport."
