Fantasy writers may have built one of the most interesting Claude + Obsidian workflows yet.
Not a second brain.
A world engine.
One vault stores kingdoms, characters, histories and magic systems.
Every new character automatically inherits existing geography, politics and relationships.
New ideas no longer start from a blank page.
They grow from everything that already exists.
The interesting part isn't AI writing.
It's continuity.
Most fictional worlds eventually become too large for one person to fully remember.
A connected vault turns lore into a living system.
One new note can instantly connect to dozens of older ones.
The productivity crowd wanted AI to organize their thoughts.
Writers used the same tools to build entire realities.
Same stack.
Completely different outcome.
