Glamour – but not (quite) as we know it

Glamours feature strongly in tale of Clay for Ellen.

But that’s my English word.  What do the people in the tale mean by a glamour?

They mean it in the modern way – partly – in the sense of greater attractiveness, though there’s no gender to this, men and women both use glamours. (Can a modern man be glamorous? Discuss.)
But they also meant it like our older use of glamour: an enchantment or magic spell.

So glamour means: an enchantment to change the appearance of a thing, in accordance with someone’s wishes. (The wishing bit is important.) I could have given this a made up word like, I don’t know, yzyzyzt, but I decided that glamour was close enough.

Oh yes. And why did they use glamours?
Just like modern glamorousness, for the strong effect on others.
Think makeup!
