House Oprah is the oldest of the three houses, founded at the same time the hallway of doors came into existence and began to be used. It's the house of the Void between Space and Time, likely the most mysterious of the three voids for its unusual properties of allowing those within to see anything they can imagine or desire, allowing them to interact with it for as long as they want - as well as its time breaking properties.

Unlike the other two houses, House Oprah doesn't follow a specific, ritualistic schedule tethered to a specific god or the power, but instead follows the blessings of their void and the luxuries it provides them - the safe passage between alternate universes, the lack of passing time, the natural healing aura and the ability to grant the person anything they desire - at the cost of them not being able to take it outside of the void, and nobody else being able to see said thing.

The house is ran by a single ruler, Akka Lune, a kookaburra Alkonost who couldn't take her job less seriously if she tried. The house's base is situated in the Etheral Oasis in Kokubu, a large array of heavenly gardens littered with small residences and attractions - from bars to potion breweries. This place is also known for being the largest natural space time rift site, and those resident to the location use this to their advantage on their void travels.
