Otherwise, a basilisk will live on for hundreds of years.
House Elves - House elves have very strong magic but use it rarely. They are very dangerous when they are not owned if they use their magic for evil.

They usually serve rich families, despite the fact that they don't get paid. House elves can only get freed if their master hands them a piece of clothing. Then they are free and do not have to do anything for their master anymore. House elves are so loyal that whenever they show any sign of unloyalty they feel very guilty and usually punish themselves (painfully). House elves can get drunk for drinking butter beer.

They guard the wizard prison on the island of Azkaban, just to keep them away from the inncoent. They wear black robes and hoods over their heads.

These spiders all tend to stay together as when one spider lays eggs there are hundreds of eggs eah time. They also stick with each other in times when they feel defenseless.

They live away from humans and contact with the outside world and tend to be found in forests, caves, etc.

If you walk through a ghost it will feel like you have just had a very wet shower. Ghosts miss eating so foods that smell strongly are the closest thing to eating for ghosts. When someone dies they only stay on earth as ghosts if they died unhappy. They can talk under water and travel through pipes. Although ghosts are already dead they can become petrified by looking into the eyes of a Basilisk. If you're a wizard and you have never seen a ghost then you are not an average magical person.
