Mirielle nearly doubles over in pain, but raises her head to snarl at Larshon. "Liar. You know as well as I that my master despises the Wall and that the only reason it remains is that it was forced on him. You also know as well as I that the torment that created this poor creature was inflicted by your mistress's servants, not Kelemvor. You are an odious being, less than a worm, consorting not only with demons but the abomination of the Ushemoi. You are barely worth fighting."

She steps back behind Alaister and, drawing another vial, hurls it at Larshon.
