Halorium is the second most populous colonial city in the Roman Empire, behind the Indian metropolis of Hastinaporum. Settled on the south end of Manhatta island on July 1, 1631, the city of Halorium was originally known as New Alexandria. As the city expanded through government funding, the newly appointed Governor of Audenisonea, Lucius Halorius Macedea chose the city, one of only seven cities on that part of the continent, as his province's capital city and renamed it after himself, Halorium. Originally the only provincial capital in North Columbia, and in a very advantageous geographic position, the settlement's population and size swelled and by the time of the Great War, had more than 2.7 million inhabitants, almost superseding New Rome as the largest colonial city.
