The timelines
Each decision spins a new thread. Worlds drift apart, each carrying its own truth.
Scene 05
Infinite endings
Six endings wait at the edges. One is secret. Most readers will never find them all.

Mara Voss
Keeper · cast by Spark
Salt crusts the rail as Mara counts the flashes — three long, one short. The sea is signalling back.
The canvas
This is what one story looks like.
The real branch map of The Keeper & the Tide. Starlight is the path most readers take. Paths rejoin: a branch can come back.
Choice points
Each node is a fork. Spark suggests options; you decide which survive.
Diverging timelines
Branches carry their own state — a character lost in one path is gone for good in that timeline.
Many endings
Hopeful, tragic, secret. Every leaf is an ending a reader can reach — and rush back to change.

The reader
Reading becomes a choice you make.
No menus, no manuals. Readers swipe through your scene and tap the path that pulls them. Choices are weighted live, so they feel the pulse of every other reader in the story.
- Swipe-native, one-handed reading
- See how the crowd chose — or hide it for a blind run
- Rewind any choice to chase a different ending
Immersive mode
Stories you don't just read. You enter.
Tap play and Spark narrates in a voice you choose, while the backdrops it painted drift behind the words. Keep scrolling — this is that screen, on stage.

The lamp had burned for two hundred years — and tonight, something answered it from below.
Beneath the tide the door hums like a struck bell, warm where the ocean should be cold.
It opens onto a sky that has never heard of her stars — and a shore where someone is waiting.
