History and specifics
The founders of the colony wanted to make it a replica of Scotland and thus had all of the cornerstones from each building brought from Scotland. Much of the colony's buildings, fashion and even vegetation were chosen specifically to remind colonists and visitors of the Scottish origins of Caldos.
The colony required a weather modification network in order to keep its climate stable.
As of the year 2370, the colony was governed by a non-Human named Maturin, although he and his family had spent time on Earth in Scotland. Many of the colony's inhabitants were Human, including Ned Quint and Felisa Howard, Doctor Beverly Crusher's grandmother. (TNG episode: "Sub Rosa")
