The poision was a advanced paralyisng poision that she was going to use on Mercer so she could hand him over to the guild and make him pay for what he had done. Without that arrow the hero would have died from blood loss.

Just because he is DragonBorn doesn't mean he is the centre of the world. How about tiber septim( aka talos). he was the dragonborn and also the center of the empire.
