If we're going for realistic, howcome we haven't seen any links yet?
Because I'm a medieval hobbyist, not a medieval scholar, and I'm going off an understanding based on a lifetime of relevant fiction and growing up with a medievalist, rather than any actual research.
However, I believe if you asked any of the actual medieval scholars on the board, they'd tell you the same thing, and be able to cite sources.
(At least, to the extent that one
can cite sources to support, "This
wasn't something that people did." That's asking to prove a negative.)
