Locusta

Locusta or Lucusta (died 69), was a notorious maker of poisons in the 1st-century Roman Empire, active in the final two reigns of the Julio-Claudian dynasty.

Locusta's career is described by the ancient historians Tacitus (Annals 12.66 and 13.15), Suetonius (Life of Nero, 33 and 47), and Cassius Dio (61.34 and 63.3).

[7] After Nero's suicide, Locusta was condemned to die by the emperor Galba during his brief reign, which ended 15 January AD 69.

[9] In the novel The Count of Monte Cristo (1844) by Alexandre Dumas, the poisoner Madame de Villefort is frequently compared to Locusta.

Described as the "official poisoner to the court of Caesar Nero," she is portrayed as comically untroubled by the macabre nature of the service she provides.

The song ends with Locusta being executed in the Circus Maximus by being raped by a trained giraffe and then torn apart by wild animals.

Locusta manifests as an Assassin class Servant in the mobile game Fate/Grand Order, added during the FGO Arcade collaboration event in April 2023.
