Still Cities are the remnants of settlements constructed by the "ancestors," who are described as pureblood humans. These ancestors are believed to have lived in an era vastly different from the current nomadic existence of Ziemians. They built colossal urban centers that were larger than even the biggest Nomad Cities of the present day. The ruins of these Still Cities are often fragmented, and their records scattered, due to the effects of Collapses. The advanced architecture and Technology found within these ruins are a source of wonder and speculation for current Ziemians. Some factions, like the Keepers of Avalon in the Bretonian Palatinate, reside in these ruins.
