Lily did not like this one bit. The forest was not a place for students to be in during the day, let alone at night. It was called forbidden for a reason... so that almost made this lesson forbidden. Once they reached their destination, the second year didn't even think about sitting down. If they sat then there would be a possibility of not being able to get away from an attack. Totally not cool!! With every little rustle of the forest, Lily nearly froze...just like all the other students had, just not for the same reason. THIS WAS WAY TOO SCARY...

And now they were actually having a class....in the forbidden forest!! Not cool...

Ok... to answer the question. The redhead took a second to think about what the spell could mean. She noticed that it sounded like moon luna and night or something like that. Raising her hand, she quickly made a guess. "Does it make things glow like the moon in the dark? Or reflect the moonlight?" Kinda like the professor's robes...
