From the Super Mario Wiki, the Mario encyclopedia
Charles John Huffam Dickens was an English author whose works often satirized the social conditions of London while also being written in such a way that attracted the poor classes. He often worked his own personal experiences into his writings, including his life as a factory worker at the age of twelve after his father was sent to prison for his unpaid debt. His stories were also released episodically, letting him adjust the future chapters after receiving criticism from readers. He gained significant and enormous popularity for his works. He married Catherine Dickens in 1836, but after their separation in 1858, he dedicated himself to his work until his untimely death in 1870. In Mario's Time Machine, he meets Mario after Mario travels back in time to return his Inkwell to him after Bowser steals it.
Mario's Time Machine
According to Mario's Time Machine, Charles Dickens was at his home in 1843, working on A Christmas Carol, when Bowser travels back in time to London and steals his Inkwell, preventing him from continuing his writing. Mario then travels back in time himself with the intent of returning Charles's Inkwell without knowing that it belongs to him. If Mario talks to him regardless, he politely introduces himself, and Charles proceeds to analyze him, describing Mario as someone who is well-traveled, before saying that he needs to continue his work, although he invites Mario to visit him later. Mario then questions various people within London about the Inkwell, and all of them, including Catherine Dickens, freely divulge everything about him, including his past and his dedication to his work. After definitely identifying the Inkwell's owner, Mario returns it to Charles. Charles thanks Mario and his act of kindness for letting him continue his writing. Mario then asks him why he writes so much, to which he responds that he feels a sense of duty to shine a light on the wrongs that should be righted, and it also pays well.
