Attica is one of the cities of Alera. It is presently governed by the High Lord Atticus Quentin or maybe Atticus Elios, Butcher gives different names in different books. There is little else about this city in canon.
Geographically it stands on the banks of the river Gaul above the floodplain of the Gaul river system about midway between Parcia and Alera Imperia. Attica has the good fortune to be out of the direct line of march for the advancing Vord. The city is reported to be under siege in Princep's Fury but apparently survives the war.
