Pleasure-loving inhabitants of Rubicun III, whose few laws carry a death penalty applied at random.
The Edo are humanoids who live on Rubicun III, a lush and inviting world the Enterprise-D considered for shore leave. They are athletic, affectionate and openly physical, and they welcomed the crew warmly. Their peace is maintained by a strict code: any crime committed within a randomly chosen punishment zone is punished by death, enforced by Mediators.
When Wesley Crusher stumbled into a flower bed in a forbidden zone, he was condemned to die. A powerful entity orbiting the planet, which the Edo worshipped as God, protected them, and Picard had to wrestle with the Prime Directive before winning Wesley's release.
