Actually that gave me another idea completely.
The Civa Alban Realm (nation where this wall, the wall of Civa Albus, is located) is a kind of remnant of a Roman Empire analog with legions and such, but its transforming into a more modern nation and its military's uniforms are transforming from legionnaire to a hybrid of Napoleonic/Fascist (this is the rough idea: http://th05.deviantart.net/fs71/PRE/f/2011/074/b/9/comm_for_omegavision_calista_by_avionetca-d3bqas7.png (no the rosy cheeks weren't my idea 😮 )) so saying that their uniforms are made from a powerful spidersilk would allow that without sacrificing any of the protection against bladed weapons that steel armor provides.
Thanks for the springboard.
