Part of the HRE or not, the prevalence of goods originating quite a distance from Henry’s neighborhood surprised me. So much so not sure whether what the ‘natural’ or plausible boundary should be.
Distance from Sasau monastery to these armor/weaponry places of origin (per Google):
Aachen +800km
Augsburg +450km
Magdeburg +400km
Milan +900km
Nicopolis (Nikopol) +1200km
Silesia (Wrocław) +250km
Via Regia is said to have covered a considerable distance (click on ‘square’ link for wiki map)
If sabres in KCD can derive from Nicopolis, why not (merc) Serbian armor for example?
