One night each year, on All Hallow's Eve, the mindworms come out. You see, your mind is a fragile thing, easily affected by the smallest of things. The mindworms revel in corruption, latching on to you and piercing your brain. They seduce you with their distorted thoughts and then drive you to despair. However, you must never give up. Rely on humanity's best defense against that which perverts it: hope.
