A leader of the Edo of Rubicun III who welcomes the Enterprise away team in Justice and then insists that Wesley Crusher must die under his people's absolute law.
Liator is one of the Edo, the athletic and openly affectionate humanoids of Rubicun III, and acts with Rivan as host to the Enterprise crew when they visit the planet in 2364 in the first-season episode Justice.
He is proud of the peace his society enjoys and explains how it is kept: mediators patrol randomly chosen punishment zones, and any offence committed inside one, however small, carries the death penalty. When Wesley Crusher falls into a planter in such a zone, Liator regrets the outcome but sees no room for an exception.
He is plainly shaken when Picard argues that laws applied without exceptions cannot be just, and when the Edo's orbiting god finally lets the visitors leave.
