The book has many passages, but there can only be one to read now; the Marshal summons up his faith and pours it forth at the vampire as he reads the sermon of the casting out of the shadow from the book of law:
"And the shadow came upon man, and the gods saw that the shadow was foul, and did cast it out"
"And the shadow was wracked and torn asunder and cast from the world of men...."
"Praise Haelyn that is highest, praise Erik lord of life, praise Nesirie guardian of the fallen, praise Avani lady of light, praise..."
OOC: Not quite an exorcism, but the casting out of the Shadow World from Aebrynis (bound to be covered in the book of law and ascribed to the gods - basically trying to weaken the vampire /support the others)
