The game begins with Simon P. Jones arriving at Mt. Holly Estate, where he has set up a camping
tent outdoors. Though not explicitly told to the player, the estate is located in the
realm of Fenn Aries, one of numerous city-states on the
low fantasy,
parallel universe planet of Mora. While superficially similar to Earth, major differences in technology include commonplace use of
airships as transport, and a building technique called "drafting" that is able to materialize and disintegrate individual rooms on a space-time level. As Simon traverses the estate, he is able to view various clues to the world's history. While censored in its typical form, a secret original copy of a history book explains the realm's past: the formerly peaceful realm of Orinda Aries, named after that world's paragon, or angel, of royalty, was overthrown by an uprising — the Fennsurrection — led by nobles from the cities of Fenn and Oris who opposed King Desilets III's generosity towards commoners. After the War of Ruin, the highly unpopular Desilets IV was forced into
exile, and the traitorous General Teskin set up an
authoritarian regime under the name of Fenn Aries. The original black color of the Orinda Aries
sigil was changed to red. This in turn provides a basis for solving the disappearance of Simon's mother, the
children's book writer Mary Jones, who wrote under the
pen name Marion Marigold. Angered by the government's oppression, including its censorship of
The Red Prince, a book about Simon's childhood obsession with the color red whose ending of him seeing the blue sky was deemed a political statement - Mary joined the Children of Black Water, an Orinda Aries restorationist
resistance group. After stealing the ruby crown of Orinda Aries in a major heist, she fled the country, hoping that Simon would discover the clues one day. Sinclair was an accomplice in the heist, and was later blackmailed by the estate's disgruntled gardener, Denny Revane, using stolen letters from Room 46. Reaching the
antechamber to the 46th room allows Simon to access the estate's inner sanctum, which contains remnants of a mining operation that stumbled upon ancient Castle Orindia, the original capitol of Orinda Aries. Simon also realizes that the 46th room contains the stolen crown, though the rubies have been replaced with sapphires, making it the Crown of the Blueprints. Using the crown and other items, Simon can reclaim the original Orinda Aries throne by drafting the castle's throne room, making him the eponymous "Blue Prince". He can subsequently go on to find the secret will of the manor's original designer, Baroness Auravei. ==Development==
