Trinsic is found in the southern region of Britannia, along the eastern coast. Fresh water is supplied through a river delta, doubling the size of the fish market thanks to the city's proximity to the Cape of Heroes. Trinsic is like a larger version of Serpent's Hold -- one gigantic stone wall surrounding the city that completely borders the interior keep.
Nearly the entire city is made of stone, from the reinforced outer walls, to the inner castle, to the shops, homes, and schools in between. The overall style is the traditional Britannian keep, with parapets, battlements and buttresses for the main walls, and solid rock foundations for the private buildings.
