World-building as composability

Build Little Worlds

A home for tiny, durable pieces of imagined worlds: spells, terrain, rituals, rules, constraints, institutions, economies, interfaces, and narrative mechanisms that can snap together into something larger.

Concrete Pieces

Magic spells, landmarks, species, weather, materials, maps, tools, and terrain.

System Pieces

Rules, economies, institutions, rituals, incentives, histories, and patterns of power.

Stranger Pieces

Interfaces, taboos, metaphors, habits, failure modes, obligations, and ways of knowing.

What Comes Next

This is a public placeholder while the site takes shape. The first full version will support learning, collecting, and combining small world-building units. Private access and member workflows will come later on infrastructure built for authentication.
