The Observatory
Five solids, one inside the other. Turn them until the stars agree.
The Aster Bequest · Season I

A genius hid his fortune in lines of light. Follow them.

Everything I built, Aster Works and the Underlay itself, goes to the one who finds my Keystone.
I · The Will
Julian Aster designed impossible buildings. Then he vanished for thirty years to build the Underlay: a hidden layer of light, memory and geometry laid over the real world. The night he died, his will went out to everyone.
“Everything I built, Aster Works and the Underlay itself, goes to the one who finds my Keystone. I hid it where I hid myself.”
Julian Aster, the Architect

The Architect · 1931–2026
He drew cities as a boy and built impossible ones as a man. Then he disappeared into his own design.

OBELISK Group
His former partner. Crane's AI agents, the Adjusters, are already inside the Underlay, and they don't play fair.
His daughter
Together they designed a city of light. Then she was gone, and he never spoke of her again.
II · The Underlay
Your phone becomes the Lens, a brass-and-glass instrument of Aster's design. Through it, the streets you know show what he hid: lines of light, his sigils on old walls, and doors where there were none.

Move the Lens over the city

Two circles of smoked glass in one brass frame: the vesica piscis, the first door. New filters come with the story: light, sound, time, heat and memory.
The Architect asks for the world: “Show me a circle that holds water.” Your camera answers, and a memory opens. Every sighting can be solved at least two ways, wherever you live.
Where his lines cross, real places around the planet open special rooms and season events. Always optional on the story path.
Step through a door into a handcrafted 3D room built from his life: twenty to forty-five minutes of story, mechanism and light.
III · The Language
Circle, line and ratio. The Underlay is built from sacred geometry, told as art, mathematics and history: Euclid and Pythagoras, Plato's solids, Islamic girih, Gothic rose windows. Every lock is a real construction, and every puzzle is fair.
Draw it with a compass
Two circles, each through the other's centre. The first door, and the shape of the Lens.
The five keys
Each act's key is a solid. Assemble them, unfold them, turn them to the light: their shadows hide symbols. The fifth, the dodecahedron, Plato's shape of the cosmos, is the shape of the Keystone.
Draw real constructions with the Lens to open his locks.
Find φ in a room's architecture, then in your own street.
Assemble, unfold and rotate them. Their shadows speak.
Tune the brass plate until the sand draws his sigil.
Turn the rose window's panes until the pattern is whole.
Complete girih and Penrose floors, one tile at a time.
Trace them in AR on a real floor, or walk them in a room.
IV · The Rooms
Every memory is a handcrafted 3D room. Turn it, take its mechanisms apart, follow its light. Each one hides part of his story, a clue to the next key, and secrets for those who look closer.

1962
Five solids, one inside the other. Turn them until the stars agree.

1971
A room that listens. Find the note, and the sand finds the shape.

1983
Turn the panes. When the light is whole, a door opens.

1996
The night he vanished. Walk it slowly.
The Prologue and Act I are free.
V · The Race
Every season opens a new wing of the Underlay and a global race: three keys, three gates, one Keystone. The first to open each gate is named forever in the Hall, and everyone else can still finish.

The Hall · Season I
First to open Gate I
This line is still empty.

You are not the only one hunting. OBELISK's AI agents occupy nodes and rooms, set traps and leave false clues. Push them out with puzzle duels, alone or with your guild.
