Descendants of the Colonials, who have managed to escape their miserable existence and become benevolent hive minds.
Anthropomorphized Anatomy: The Modular People are a version of this-they're an entire race of sentient, hyper-specialized "organs" that perform one specific function. Individual Modulars pile themselves together to form a single mobile entity, which can swap individual organs with any other Modular to fulfill a specific task or function.
Crippling Overspecialization: Played with. Their hyper-specialization puts them in a situation which more-or-less forces each of them to partake in a peaceful, efficient society in order to survive as they quite literally can't live without each other. Thus they avoid the evils of conflict, poverty—and individualism or ambition.
No Poverty: Their society is said to be a fully equal one, where no one lacks for anything.
Starfish Aliens: The Modular People are walking colonies of smaller organisms, all of which carry out a specific task.
