Nefronium is a bizzare yet extremely volatile element. It is purple in colour and has a direct link to hell. It is one of the most dangerous elements ever to exist as it can react with almost anything. Those who come into contact with it tend to die horribly and slowly.
Link with HellEdit
Nefronium originally came from hell. When the dimension of hell split, Nefronium poured out and most of it landed on Planet Aren. Those who could control Nefronium had to be exceptionally powerfull. Those who do control it also have the ability to enter hell and leave. They can also send people who came from hell back. this however takes a great deal of energy.
