Detached

A detached race is a race that has lost his ability to feel normal stimulation.

Usually a race reach this status because of cybernetic or thought sharing.

Most races reach this status and the end of their life cycle, usually before leaving the universe or creating a simulation in which live. It's rare, but it's confirmed that some races have let themselves die, or they ignored invasions.

Invading a detached race that has no interest in defending itself is usually not considered a crime by the Polite Galaxy ideology.
