Scion of Murgen (He/Him)
Yes. 5 Torches Deep, as one of its idiosyncracies, uses the more accurate terms arming sword and longsword rather than longsword and greatsword.I do not have the old D&D manuals but my impression was the D&D broadsword is what is no referred to as an arming sword.
Whereas what are now (in historical circles) as broadswords are weapons that are also descended from the arming sword with similar hilts and guards as rapiers but beefier blades more suited for cutting. I believe at the time the English referred to these military swords as great swords or war swords.
