Colony

A colony was an area settled by individuals from a different area on a planet, or from another planet.

Colonies on Earth
The West Indies were colonies of the British Empire by 1746, during the reign of King George II. That year, the English solicitor Grey led a scheme to transplant Scots there under the false impression that they would be able to work off their passage after seven years of labour. In fact, the Scots were really being made slaves to work plantations there. Had the Second Doctor not intervened, Jamie McCrimmon and Ben Jackson would have both ended up in the West Indies as slaves. (TV: The Highlanders)

While visiting Villa Diodati in 1816, the Thirteenth Doctor stated that she and her companions were from the colonies. When Ryan Sinclair played "Chopsticks" on the piano, Mary Shelley asked him if the tune was popular there.

Byron agreed, believing that the Doctor was from somewhere "much, much stranger". (TV: The Haunting of Villa Diodati)
