!Main Characters

'''[=NiGHTS=]'''

The eponymous character of the series, [=NiGHTS=] is a carefree, mysterious being that flies around the world of dreams. They're interested in anything new and unusual, including Visitors, and tends to do their own thing, for the most part. [=NiGHTS=] has a tendency to be unthinkingly rude, especially towards Owl, but they generally act in fun, and means no harm.

Instead they bring out the positive traits of the Vistors, that are hidden deep down, and makes it part of it's own personality. Will's determination and Helen's bravery for one.]]

* GodIsEvil: He's really the only character implied to be a god, and being able to create Nightmare and the Nightmarens certainly attests to that. The evil part comes with his being the BigBad.
