Thanks. I looked into that third picture a bit of the OP in search of that stabbing weapon and I found an actual picture of one (I thought it'd be about as large as a gladius but it's actually much larger).
You can see it clearly in the center there.
The source refers to it as a "Moorish Boarding Sword" (14th - 15th centuries), so I assume it was mainly used by sailors, marines, naval soldiers, etc.? Not sure if it's worth including in the mod, but it's certainly something unique.
