- "What did you accomplish, boy? A bolt loosened in Starrick's machine, a large bolt... but not enough! [...] The mechanism we have built has been going strong for a hundred years and will run a thousand more. It is the very city itself."
- ―Ferris on the Templars' power over London, 1868.[src]
Through his enterprise, which had laborers work tirelessly to increase profit and production, he ensured Grand Master Crawford Starrick could exert his control over the industries of London and beyond.
- "Mr. Ferris has made note of our declining production. He demands that more iron be produced each day! No time must be wasted!"
- ―An orator relaying Ferris' orders to his workers, 1868.[src]
Since 1862, Crawford Starrick purchased the Ferris Ironworks, which became part of the Grand Master's vast empire, and Ferris himself joined the ranks of the Templar Order. As a result, Ferris' wealth greatly increased; he subsequently spent a large part of it on a charitable society and a local brothel, though the former is thought to have been mere lip service on Ferris' part. For his Templar affiliations, as well as his appalling treatment and usage of child workers, Ferris was targeted by the British Brotherhood of Assassins.
In February 1868, Ferris, after dealing with an injured child worker, returned to his office. There, he dictated a letter for Starrick to his secretary, informing the Grand Master that he had secured a source of iron ore that would supply them for years to come. After the missive had been written, Ferris spoke with his secretary about the health of the latter's father.
Shortly thereafter, the Assassin Jacob Frye assassinated Ferris for his role in Starrick's schemes. As the factory owner lay dying, he mocked the British Brotherhood for its refusal to engage with the Templars in London. Once Ferris breathed his last, Jacob dipped a handkerchief in his blood, before making his escape.
- Rupert is a Low German form of Robert, which can be traced back to the Germanic name Hrodebert. Said name means 'bright fame', being derived from the Germanic elements hrod 'fame' and beraht 'bright'.
- The surname Ferris is an Anglicization of the Old Gaelic name O'Fearghusa - a compound of the Gaelic O, meaning 'grandson' or 'male descendant', and the personal name Fergus, composed of the elements fear, 'man', and gus, 'vigour, force'. The name is also similar to the word ferrous, possibly referencing Ferris' position as factory owner of the Ferris Ironworks.
