You tear a page and fold it into a neat origami castle. When you set it on the floor, you and a number of creatures equal to your level shrink and disappear inside. The tiny paper castle is an extradimensional dwelling as described below, with a 8-ft tall door that leads from the extradimensional space back to the prime material one. A creature exiting the plane appears in the nearest unoccupied space next to the paper castle. The paper has 25 AC and 1 HP, and is invulnerable to psychic damage.

Beyond the door is a magnificent foyer with numerous chambers beyond. The dwelling’s atmosphere is clean, fresh, and warm.

The palace is furnished and decorated with comfortable, multicolor furniture that creates a cozy atmosphere. Rainbow stained glass casts fragmented, colorful light from each window. It contains sufficient food to serve a nine-course banquet for up to 100 people. Furnishings and other objects created by this spell dissipate into smoke if removed from it.

The door opens to a small entrance room, with great double-doors that open to a long hallway. Many wood doors flank the sides of the hallway behind pillars of pale stone carved with flowering vines and butterflies. These doors lead to guest bedrooms and baths, a kitchen and dining hall, a small ball room, and other rooms described below. It ends in a circular room with a seating area at the base and two spiraling staircases up. Upstairs there is a more intimate sitting area with a pink-flame fireplace, master bedroom with an adjoined wardrobe and master bath. A balcony from this bedroom overlooks a garden, which can be accessed by another door on the floor that leads to the hallway where the guest suites are. The garden has bright, multicolored plants and slightly bluer-green grass, with plenty of pink and green flowers. 

Den. A small apple tree grows out of the center of a sunken seating area, with many mismatched cushions and blankets. A creature that ingests an apple is poisoned and sent to a euphoric, drug induced haze. They gain +2 to CHA and -2 WIS for one hour during this state. A Lesser Restoration spell or greater removes this effect. 

Aquarium. A room entirely filled with water is magically held together behind one door. It's filled with plant life, algae and reefs, small tropical fish, axolotl, seaweed, turtles and other aquatic life. A large rock is in the center of the water, which is lit by filtered sunlight, with a small indent perfect for perching.

Library. A two floor personal library with a rolling latter. It is comprised of all the random bits of information an Archfey has collected, either by learning, bargaining or stealing, including people's names, memories, identities, and other Legally Owned information the Archfey possesses. The door to this room is locked by an Arcane Lock spell with a password of your choosing. This includes memories, identities and information owned by the previous entities of the Archfey Spark, including their thoughts, feelings, lives and memories. The current spark's entity's thoughts, feelings, lives and memories materialize as books within the library.

Tea Room. You fall into this room, gently landing on the floor of the ceiling, where a sitting area was upside down. A cozier sitting area with ten mismatched chairs and a coffee table stocked with fresh tea and ten mismatched teacups. Bright window cast prismatic light into the place, and small multicolored strings and fabric strips dangle small bells from the ceiling. One window is open, and a small, soft breeze occasionally blows through from the ambient light nothingness of Magic and twinkles the bells.

Gazeebo. A smaller, more intimate garden with a nighttime darkness to its edges. Thousands of butterflies occupy the garden, fluttering in gentle moonlight. A gazeebo sits a small way down a garden path, with a bench.

Fizzy's Bedroom. Besides the grand, proper bedroom, is a small door hidden in the back of the grand bedroom's wardrobe. This door leads to the bedroom of Fizzy, a tiefling warlock, as it were when she lived in it. Fabric strips dangle down from a fishnet ceiling in the small mismatched shack. This door is also locked by separate Arcane Lock spell, with its own password.

A staff of 100 small faeling servants attends all who enter. This includes faeries, gnomes, harengon, bullywugs, campestri, and quicklings, with distinct personalities and a capacity for memory, though they are nothing but pure magic. They are invulnerable and obey your commands happily. Each servant can perform tasks that a human could perform, but they can’t attack or take any action that would directly harm another creature. Thus the servants can fetch things, clean, mend, fold clothes, light fires, serve food, pour wine, and so on. The servants can’t leave the dwelling.

At 13th level, the demiplane solidifies itself into reality. The paper palace lasts until dispelled or destroyed, and is a permanent demi plane. Objects can be stored inside it, but objects originating inside the dwelling still turn to glitter if removed, and fey servants must stay inside the castle.

The front door of the palace can be turned with a special key. Each direction corresponds to a different location: once clockwise opens it to the prime material plane where the palace lays, once counterclockwise opens it to the Sparkholder's room in the respective castle of the respective court. The bedroom door lock in the court room can be turned counter clockwise to enter back into the palace.
