Magic Eraser (Redux)

Magic Erasers
Magic Erasers are a type of magical item that allow the user to remove any spell cast upon them. Their use is limited by how many spells they can erase at once, and each time they're used it takes away some of their power. This makes them useful for cleaning up messes but also dangerous if misused. They were invented in 2035 by Dr. Christopher Jansen, who was inspired after witnessing an explosion caused by a spell gone wrong. He wanted to create a device that would prevent such accidents from happening again. He created the Magic Eraser using nanotechnology and nanobots which he injected into his own body to give himself superpowers. These microscopic machines allowed him to absorb other people's powers through contact with them, including the ability to erase spells. Dr. Jansen hoped to do good in the world this way, helping those who needed it while avoiding conflict with others. Unfortunately, he overestimated both his abilities and the dangers of his invention. When his ex-wife found out about it she tried to have him arrested, claiming that he was threatening her life. In retaliation, Dr. Jansen went on a rampage and wiped out half of Los Angeles before being stopped by the hero known as Mr. Miracle. Once apprehended, Dr. Jansen agreed to give up his research unless there were no charges filed. The authorities didn't want to arrest him due to fears that he might destroy more of the city, so they gave him a small island where he could continue his work. His goal was to make the world a safer place through technology rather than violence. The first Magic Erasers were sold for $1,000, but they quickly became a popular item among superheroes and villains alike. The cost dropped over time until they were available almost anywhere. Due to their popularity, their manufacturing process is now automated and has been made much cheaper. Since then, many other manufacturers have come out with similar products. Many of these are inferior copies of the original, though, and only the original Magic Eraser brand is considered effective.
