Brutus, was prophesied to be the doom of his parents, which came true; his mother died in childbirth and his father in a hunting accident by Brutus’ arrow. For the crime of patricide he was exiled from Italy, and with followers he sailed to Britain.
They reached an island that was uninhabited save for Giants and Faerie folk. Brutus made war upon the giants, wiping most of them out and taking the island. After many years, the island was named after Brutus, known today as Britain; and with his followers as Britons he built a great city, Troia Nova, from which the Trinovantes tribe took their name, though that city is now called London City.
Brutus ruled wisely and well, and after he died, his sons split the kingdom between them: Locrinus got Logres, Albanus gained Alba, which is now known as Caledonia, and Camber’s portion was Cambria. The lord
Corineus had already been rewarded with the peninsula that we now know as Cornwall.
