Lyra used the threes and to climb around and hide for everyone else. They couldn't see her but she could see them. She moved around and killed a few little monsters and then dragged them away from the path that was made clearly so they wouldn't be noticed by other people. She then heard someone and went out to see who it was, she saw a human.. Or wait, he had wings? What was he? She got curious but didn't get down. 

She kept an eye on him and climbed from three to three and saw he was going to a village. She looked at the tiny leather bag that she wore around and opened it, a few pieces of gold where in there and so she jumped down, landed on her feet and hide in the bushes from the human.
