Lux Aurea is a city in the American animated series 'The Dragon Prince'. The etymology of the city's name derives from the Latin "Lux", meaning "light" and "Aurea", meaning "golden". It translates to "Golden Light".
This name is also used in Portugal where it is spelled Áurea (with accent). It seems to be trendy in Portugal, probably due to the popularity of the singer Áurea. [noted -ed]
