And thanks for reporting the error!
You're welcome!
I'm a bit confused by the sword. The others are plausibly valuable enough to start a war over, with the possible exception of the ruby - which reads as targeting 'the owner' rather than 'anyone it's used on', I think because it's a valuable - but the sword seems more like a weak loyalty test, or perhaps a tool for navigating courtly intrigue, which seems ill-fitting for a sword. Perhaps you could share your thoughts on the matter?
I envisioned the sword as a sort of loyalty test, yes. If you have this sword, you definitely know how your subordinates feel about you.
The idea behind the ruby is that people go through a lot of shit if they're convinced they'll be satisfied in the end. And here's a magic stone that can guarantee you'll feel that way!
(EDIT: Although if you wanted to read it as the ruby making other people satisfied, that's still a great plot hook.)
