Aurelia was not able to lift a finger nor summon her ability because the pain was incapacitating. The effect of iron on Fae makes them unable to apply magic to their wounds quickly enough to heal before bleeding out. The poison from the iron was killing her faster than she could heal and she would need a healer to increase her chances of survival.
With a grunt, she placed her hand on the hilt and tried to pull it out but Rosalind chided her playfully,
"Ah-ah, if I were you, I would not pull that out and die faster. That is a fatal spot and any movement would worsen the whole thing. If you're lucky enough, you'll be found while I'm gone. And if you're not, well, I guess that depends on your luck," She bowed dramatically," It was a pleasure working with you, Aurelia. "
With those words said, Rosalind went back to the place where Islinda was bundled up and hoisted her over her shoulder.
