The steward is a Toad who makes an appearance in Paper Mario: Sticker Star. He resides at The Enigmansion as a former owner and a current servant to its present owner, the forebear. According to the steward, he became the owner of the mansion once its previous steward passed away. As both a steward and servant, he shows great hospitality toward Mario and the forebear.
During the events of the game, the steward's mansion becomes haunted as a result of many Boos being released from the Book of Sealing, and he gives Mario the task of finding them all and sealing them back into the book. After this is done, the steward will give him the Forebear's Portrait as thanks, allowing Mario to access the ski lift at Whiteout Valley.
If Mario decides to return to the Enigmansion after riding the ski lift, he will discover that the forebear has returned to the mansion and regained ownership, making the former steward his servant.
The steward is first seen at the beginning of W 4-3, The Enigmansion, where he is sitting outside on the porch in the middle of a snowstorm. Once Mario approaches him, he introduces himself as the steward of the mansion. He gives Mario the offer of enjoying comforts of the mansion, but says that it is impossible at the time, as a book containing terrifying creatures has been opened, releasing the creatures within, causing him to flee the mansion. As proof, he shows Mario the Book of Sealing, the book which contained the ghosts. He then gives Mario the task of capturing the ghosts back into the Book of Sealing and returning it to its rightful place, allowing him to resume his duties and treat Mario with the hospitality he deserves.
Two of the Boos which Mario must capture involve the steward. If Mario exits the mansion, he will find the steward by a bonfire, struggling to get warm. His chills turn out to be because of a Boo hiding behind him, which is revealed when Mario hammers out the flames. After the Boo is defeated and sealed into the book, the steward says that his chills have gone away as though they were never there in the first place. Another Boo requires Mario to remove a portrait of the steward blocking off the second floor and replace it with the Mansion Door, then move the portrait to a bedroom on the second floor, so that the Boo inside becomes visible and can be battled and captured.
After capturing all the Boos and defeating the Big Boo in the basement, Mario places the Book of Sealing back on its pedestal, returning the mansion to its former state. The steward appears and tells Mario that the paranormal activity in the manor has disappeared completely. He invites him to a room near the lobby, where he insists they sit down and chat. After Mario inspects a picture on the wall, the steward explains that it was painted by the previous proprietor of the mansion, who has passed away. As a token of his thanks, he gives Mario the Forebear's Portrait, saying that he feels better without it and that he may put up a picture of himself in its place. Mario can now activate the ski lift at Whiteout Valley, where he will meet the forebear himself.
If Mario decides to revisit the mansion after taking the ski lift, he will discover that the forebear has returned and reclaimed his position as the owner of the mansion. He calls in the steward, who is now his servant. As further thanks, the steward gives Mario an HP-Up Heart.
The steward is later seen near the end of the game along with the forebear at the revival of the Sticker Fest. In addition, the steward and forebear appear together in the end parade, where they can be seen inside the mansion on the World 4 float, having tea while the Big Boo pops out from behind and a group of Boos circle them.
