and yes, he's close to caligula.
'born Gaius Julius Caesar Augustus Germanicus in 31 AD, was the Emperor of Rome between 37 and 41 AD. Known throughout history as a cruel and erratic ruler, his reign would end when he was killed by Cassius Chaerea and the Praetorian Guard at the Palatine Games.
There are few surviving sources about the reign of Caligula, although he is described as a noble and moderate emperor during the first six months of his rule. After this, the sources focus upon his cruelty, sadism, extravagance, and sexual perversion, presenting him as an insane tyrant. While the reliability of these sources is questionable, it is known that during his brief reign, Caligula worked to increase the unconstrained personal power of the emperor, as opposed to countervailing powers within the principate. He directed much of his attention to ambitious construction projects and luxurious dwellings for himself, and initiated the construction of two aqueducts in Rome: the Aqua Claudia and the Anio Novus. During his reign, the empire annexed the client kingdom of Mauretania as a province.
In early 41, Caligula was assassinated as a result of a conspiracy by officers of the Praetorian Guard, senators, and courtiers. The conspirators' attempt to use the opportunity to restore the Roman Republic was thwarted, however. On the day of the assassination of Caligula, the Praetorians declared Caligula's uncle, Claudius, the next Roman emperor. Although the Julio-Claudian dynasty continued to rule the empire until the fall of his nephew Nero in 68, Caligula's death marked the official end of the Julii Caesares in the male line.'
