Nachtritter

I am trying to concoct a German sounding name for a group in my next novel.

Nachtnebeldunkelritterbruderchaft.

It is supposed to mean the Brotherhood of the Knights of the Night-dark Mist.

Does it? Anyone here speak German?

Their shorter form is Nachtritter, which I am hoping means Night-rider (or, literally Night-knight)

Anyone? Bueller? Anyone?
