What does “imprinted” mean?
The idea of “imprinting” is choosing the soul’s other half. It’s like something they can’t control but when they see someone else they know that person is going to be the one they spend the rest of their life with. It’s not quitting the group, but once they find their “imprinting partner”, they wait until they are ready to settle down, and then they stop being werewolves so they can grow old with those they have imprinted on.
