"My names Alicia, and i er..... i was looking through my fantastic beasts and where to find them and i was er.... wondering wether the lethifold or "living shroud would be one..... They remind me ever soooo much of a dementor... Only the patronus charm can repel them, and they make their victum cold." "they also suffocate their prey!" "they also resemble a black Cloak" *alicia looks around excitedly now and says "Is there any way the dementor and the lethifold could be related????"
