Sejanus created an atmosphere of fear in Rome, controlling a network of informers and spies whose incentive to accuse others of treason was a share in the accused's property after their conviction and death. Treason trials became commonplace; few members of the Roman aristocracy were safe. The trials played up to Tiberius' growing paranoia, which made him more reliant on Sejanus, as well as allowing Sejanus to eliminate potential rivals. Victims of this reign of terror related to the imperial family included Gaius Asinius Gallus Saloninus, second husband of Tiberius' first wife Vipsania, who had since died, and Decimus Haterius Agrippa, grandson of Agrippa and husband of Augustus' great-niece, Quinctilius Varus.
