The Colbat City used to be called Old Tal'Erj, before travellers marvelled at the grandeur of its Cobalt-blue stonework. Its perimeter represents the limits of the initial city of Tal'Erj, before its rapid growth. Nowadays, it is mostly composed of large guild halls, ancestral open-air markets, residences for the oldest Tal'Erji families and officials, as well as some of the most famous and powerful merchant groups.
