Barrel Of Safety

This barrel is around the size of a normal storage barrel, 4ft wide by 4ft long. Whenever the lid is removed, the inside of the space will appear to be black and empty. If someone chooses to enter the barrel, they will find themselves in a room that is dependant on the person's personality and what path they decided to take (Class and backstory.) The barrel only has one weakness, magical attacks. If the barrel is destroyed then anyone inside will be tossed to a random plane of existence.
