Question:Why describe it as a broadsword when a blade of that length fits the definition of a greatsword?

Question: does the sword fold or collapse in any ways? if not, does he always carry it?

Question: why call them coin shaped ingots and not simply iron coins?

Question: Why do you use the same character for all of your roleplays?
