There's also the whole civilization eastward who had to build a system to contain the dead.Geez, ive really been low balling how dangerous those things are.
So in the West we have a vast desert and the nomadic Gold Fields to hold them off, South these angry mountains/volcanoes and a star, East the egypt flavored civilization and North is straight up ocean (and near the Maelstrom I think?).
There's no winning, only grinding attrition where everyone has to outlast the dead.
