Names.No their aren't really base on dark things of the nights or shadows. There more based off things that makes them unique. Like Waterfall, she named after her ability to control water, but she the only one in her hole family that can do liquids.
Now Kaden and Jackson on the other hand is a different story. They didn't come from an all werewolf family. They came from a vampire werewolf family. Yet Kaden in Werewolf means 'God of Fire'. So he was named after his ability to control any type of fire and Jackson in vampire means 'The Traitor'. He did once live up to his name, yet his down fall soon came when God of Fire came back and slayed him. The Traitor's packed lived on though with a female alpha.
