One of the oldest cities of the Ancient World, founded about 4500 years before Khelens.
The whole city-state was build as a huge defensive wall against
the frequent invasions of barbarians coming from the eastern steppe.
At its peak, the Long Wall measured more than 30km and was as high as 25m.

The City of the Long Wall was finally conquered
by the fourth kingdom of Haemdel in the late IIIrd millenia BEK.
It was mostly destroyed by the barbarian invasions of the XXIIth century BEK,
and its last inhabitants abandoned it soon after.
