Lego theme
Many Lego sets are part of a larger consistent group known as a Lego theme.
Perhaps the most well-known are the Legoland themes, namely Town, Castle, Space, and Pirates.
Even the original, versatile kind of sets was eventually given its own theme name, Basic. This later evolved into Creator.
