lol, I see what you mean.  Nice twist.  I think though that if Arn lets himself go too, he could enjoy the darkness.  But he cares enough for her that he would not want her in that place.  

Question, your characters seem to be following more mystical type spells while the way I understood magic posed by Merlin as more of a physical manipulation and manifestation.  not saying I am against it but just wondering what sort of rules or system you seem to be utilizing. 

Also, maybe I read it wrong but did Tyr just get stabbed through he chest or just knocked back maybe few crushed ribs?
