Demacia is a shining beacon of hope for humanity, and as such the nation and its Capital are the visual representations of this concept. There is a clean and pristine feel and look to its cities. Towering spires litter the skyline of the city. White stone and marble are the materials of choice in the construction of Demacian buildings. Majestic flags fly high along the parapets of the city. The city walls virtually gleam with power and nobility. The noble houses that reside within the city are the Sona Buvelle, Garen Crownguard, Fiora Laurent and Vayne Vayne. The Royal Palace of House Jarvan IV Lightshield is the place from which The King of Demacia reigns from. The city also has a barracks and a penitentiary. The Capital itself sits next to a natural port overlooking the Conqueror's Sea, with the majority of the other towns resting on a plateau. The College of Magic is the main center for magical learning within the Kingdom and produced many skilled mages, such as Lux Luxanna Crownguard, the Lady of Luminosity. The Golden Round is a large and lavish theater where royalty come to watch its numerous plays. Magga, a famous actress, once played on its stages.
