(Aside: I'm not sure why I like that word, "British", so much. Its just relaxing or something.)
The sword however, is the actual interesting thing, as it has runes carved into its blade presumably by the smith who made it. The runes however make no sense.
Forged in the 14th century or thereabouts, it is not an uncommon blade. Many blades bore the marks of runes or glyphs. Incantations, parables, sword names etc etc. Whatever, in short amused the maker or the commissioner.
This one is probably not any different, except that no one can read it.
It is entirely possible that the sword-smith was in fact, like myself, a horrid speller.
