The thorn is exceedingly sharp,
an evil thing for any knight to touch,
uncommonly severe on all
who sit among them
Again, my first attempt at reading this with its old original poem

I don't know about anyone else, my first read of this gets me thinking its relating to women? (thorns that embelish and protect a rose - the rose is often linked to women in history)
Its a real kick-ass kind of rune this one, there is a real sense that you are opening pandoras box if you are lured in by the rose in the first place. Sort of like if you take on a challange which presents itself, knowing full well the result is going to be bad, then you only have yourself to blame when it all hits the fan.
I am hoping you might jump in with a few nicer alternative theories as I am reading this one as a bit of a bad rune. (and still think there is a heavy 'female' influence behind all the evil stuff too!
I would like to know if anyone has drawn this rune and 'read' it in a good way?

thanks!

I thought I would come back to the rose idea. The rose itself is feminine but I think the thorn is masculine, it is the protector of the rose. Almost like protection but more primal as I feel a jealous streak through it as well, like a man getting angry because another man tries to steal his woman.
I see it as a warning, to re-think my plans as my current course could lead me to bring down the "wrath of the gods."
I haven't actually meditated on this rune yet but those are my initial thoughts based on what I have read here.
