Cabin Fifteen is Hypnos Cabin, cabin for the demigod children of the god of sleep. Their powers are strong yet underestimated due to the fact that their head counselor, Clovis, sleeps a lot. They can put people or animals to sleep, control their/others' dreams, enter others' dreams, and make sleep their foes forever, or until they feel generous. They meet with the gods a lot in their dreams. They can also wipe memories from people and expose their memories. Anything to do with sleep and/or dreams and/or memories, they can do. As you can tell now, they are pretty powerful, maybe not physically, but they are not people whom you want to mess with, or it may be the last thing you do...awake.
