There’s a character in the Dishonored series, Luigi Galvani, whose house can be robbed in the second and third missions of Dishonored 1 and the first and last missions of Dishonored 2. You never meet him in person, but he actually has a huge impact on the series’ plot.
If you read his letters, he’s the one who first realised that the import of Pandyssian rats (from whence the plague arose) wasn’t accidental. He sent an anonymous letter to Empress Jessamine Kaldwin, whose subsequent investigation into the affair precipitated her murder - because the person responsible was Hiram Burrows, her spymaster, and he was worried he’d eventually be discovered.
Basically, this dude - who doesn’t even have a character model - is responsible for the plot of the entire Dishonored series.
