Shadow Hunter Norn
From Creatures Wikia
The Shadow Hunter Norns, created by KnyteTrypper, are the next variant of his Hunter Norn series. This breed is the result of an project to cross the genetic original strain of Hunter Norns with Marcus K.'s new Ghost/Phantom Norns. Norns of this breed aren't shy about attacking grendels, but it doesn't seem to be their major purpose in life, as it is with the version 1 Hunter Norns. They don't get angry much, and get along well with other norns. Like the Ghost/Phantom Norns, when hit or frightened they turn invisible until they calm down, in worlds where Marcus' invisibility agent has been injected.
