Princess Senna is the protagonist of :devtheroyalarchitect:'s Mario fanfiction story, Subconscious. As a recent graduate from San Francisco State in Architecture and Civil Engineering, Senna takes up a construction job on Earth and is assigned to one of her first on-site jobs, to inspect a run-down custodial care facility. After finding a warp pipe disguised behind a bathroom wall, her intrigue lead her through it to the Mushroom World, where she stumbles across a forgotten island beyond Princess Peach's kingdom. There inhabit a community of the Koopa Kingdom's excommunicated minions, suffering mutations after a science experiment gone wrong in exchange for their freedom. After sparing her from a tribe of savage natives, the grand chieftain Muuhe gives her an ultimatum: "Prove your loyalty, or die". In a frenzy, Senna offers him her construction services--to reform his island and modernize it into a Kingdom. He agrees, and, impressed with her work, takes her under his wing as as one of three royal figureheads (dubbed Princess) for the network of islands they later conquer for the kingdom alongside now King Chief Muuhe and the King's hand--Champion Guiek, who is the heir apparent.
