Dynamic world creation — questions create places.
"The world grows where curiosity leads."
Core Principle
Don't pre-generate everything. Generate on demand.
When a player asks about a place that doesn't exist, create it. Questions expand the world. Exploration IS creation.
Player: "What's north?"
DM: *creates north*
Generation Philosophy
# What triggers world generationgeneration_triggers:questions:"Where did the grue come from?"statements:"There must be a library somewhere!"actions:DIG:"tunnel"CLIMB:"passage"quests:"Objective location generates itself"exploration:"Walking beyond known areas"
Methods
CREATE - Generate New Place

Directories carry behavioral defaults that children inherit:

Tower Directory Pattern
# Tower directories extend verticallytower_directory:pattern:"tower-name/"contains:-ROOM.yml# Tower exterior (storefront)-lobby/# Floor 0-elevator/# Central column (goes anywhere)-roof/# Top floor-floor-N/# Numbered floors (positive = up)-basement-N/# OR link to external skills as floors# Skill-as-floor patternskill_floors:principle:"Skills can BE floors — no duplication"method:|
Instead of creating floor-1/ inside tower/,
link to skills/some-skill/ and add ROOM.yml there.
The skill IS the floor content.
example:|
# In elevator exits:
floor_minus_1:
destination: ../../../../../skills/no-ai-ideology/
floor: -1
# In skills/no-ai-ideology/ROOM.yml:
room:
floor: -1
tower: no-ai-tower
exits:
up: ../no-ai-lobby/ # or explicit path
down: ../no-ai-bias/ # next skill in chain
Topology Patterns
Pattern
Structure
Use Case
Twisty maze
Randomized connections
Challenge, getting lost
Grid
Regular X/Y layout
Cities, chessboards
Star
Hub with spokes
Crossroads, central plaza
Loop
Circular path
Racing, time loops
Tree
Branching, dead ends
Dungeons, boss rooms
Web
Many cross-connections
Complex social spaces
Tower
Vertical stack + horizontal branches
Buildings, department stores
Tower Pattern (Yoot Tower / SimTower)
Inspired by Yoot Saito's SimTower (1994). Buildings extend vertically with each floor branching horizontally.

Q: "Where does the blacksmith live?"
A: Creates blacksmith-quarters/ with:
- Forge room
- Living quarters
- Connected to market/
From Actions
Action: DIG
Creates: tunnel/ or cellar/
- Connects to current room
- Darkness, rough-hewn walls
- Possible discoveries
From Quests
Quest: "Find the ancient tome"
Creates: hidden-archive/ somewhere logical
- Contains the tome
- Appropriate guardians
- Connected via discoverable path

Safety Guidelines
Maintain consistency — don't contradict established facts
Respect player agency — their discoveries are canon
Preserve mystery — not everything needs explanation
Allow emergence — unexpected connections enrich world

Example Session
> GO NORTH
The path leads into unexplored territory...
[CREATE: forest-path/]
You find yourself on a narrow forest path. Tall oaks
loom overhead. The trail continues east and west.
> WHAT'S EAST?
[EXPAND: from=forest-path, direction=east]
Through the trees, you glimpse an ancient stone
structure — perhaps a ruin or shrine.
> GO EAST
[CREATE: old-shrine/]
A weathered shrine stands in a small clearing...
