The Lexor family were Brujah lawmakers and a scion family of the Trinity of Constantinople, led by Tribonius. Originally Roman refugees after its fall, they were made Trinity scions under the Antonian Ventrue. They brought copies of Roman laws with them, presenting the Codex of Legacies to define the Trinity's code of rule.
They formed the Brujah Senate within the Byzantine Senatorial body as they legislated law for the whole Byzantine Empire.
