"Lethifolds and Dementors are quite similar and are repelled in the same way, however Lethifolds are a highly dangerous and carnivorous creature, does anyone know what lethifold are commonly known as?" James asked and waited for a student to volunteer the answer. "Correct, moving on. The black cloak of the lethifold gets thicker after digesting a human, as fun as that thought is does anyone know how a lethifold would attack a human?" James nodded when a student gave him the correct answer. It was no doubt something that would sit with some of his students as it had with him when he was a student.
"Moving on to Dementors which you might be more familiar with, they don't feed on bodies but rather happiness and can consume souls, once upon a time the dementor's kiss was an act used as a punishment of last resort for the worst of the worst criminals, though thankfully that is no longer in use as I'm sure you'll agree it is a fate worst than death," James let that last point sink in before he continued. "As mentioned earlier dementors and lethifold can be repelled in the same way, this is through the use of the patronus charm which you will be learning in due time," James waved his wand in the direction of the blackboard and his initial notes vanished and were replaced with the homework assignment. "Your homework is simply an essay on both dementors and lethifolds and is due before our next lesson, class dismissed,"
Assignment: RP the lesson. The first students to answer the questions will receive extra credit, feel free to complete the homework also for extra credit.
