Nadia raised her hand, "Since poltergeist are manifestation of emotions, only they would be dark when manifestating a very violent, negative emotion maybe? Such as rage, like in the example Laurasia gave? They sure look dangerous enough." Though Nadia doubted such classification would be that simple.

There were matters to consider, like, if the emotion was what made something dark or just will and factual actions. Was it possible to think of an emotion as dark? The very same definition of dark was rather blurred. For example sadness, if the spirit tried to feed of that emotion like a pogrebin would, or jealousy. The poltergeist was dark? Could it be destroyed? Should it be not, because of a philosophy of dark and light, ying and yang, perfect balance and all that?
