Grian didn't have a choice in joining the Watchers. It was either join them and never see his friends again or stay and his world would fall into disrepair. He chose the former, and while Evo is safe and sound, he is incredibly lonely. Studying the Watchers magic is just about the only thing that keeps him entertained these days but when he's invited to Hermitcraft how can he refuse such a tempting offer?! Now he just has to make sure the Watchers never find him. Easy peasy!.... right?
