Nebula energy

Nebula is an energy which holds minor relation to Space energy. It is the collection of energy particles which makes the energy look as if it is a nebula within the cosmos. Generally, it can cause choking as if dust was going into someone's lungs. It does have a higher state though, that only achieves through mastery of the energy, Nebula Bodies. It enlarges the user, giving them a burning demonic appearance, the body being made of the energy which changes colour on the body. Maintaining the form takes extreme concentration, will and energy control. The form only lasts 30 minutes and heavily drains their stamina. It causes natural spread of dust particles which make it hard to breathe over a larger scale.
