A powerful being or group of beings existing partly in another dimension above Rubicun III, revered by the Edo as their god and protective of them as its children.
The Edo God is the name the Enterprise-D crew give to an object found in orbit of Rubicun III, a vast structure only partly present in normal space. The planet's gentle inhabitants, the Edo, worship it as God and believe it watches over them and their absolute laws.
It appears in The Next Generation episode Justice. When the Enterprise investigates, a small glowing probe enters the bridge, demands to know the visitors' purpose and links itself to Data to exchange information. Data learns that the entity regards the Edo as its children and resents interference with them. After Wesley Crusher is sentenced to death for a trivial offence, Picard must weigh the Prime Directive against the boy's life, and the being blocks the transporter until he argues that no law can be just if applied without exception.
Its true nature is never explained.
