you have to go back to the first lever acctivate that and lorek should appear

how do you do chapter 14-1??

Chapter 14-1: Double tap to jump gap after killing bear and wolf. Keep going until you
come to wall to break down, Lyra behind it. You will be attacked as you break down wall. 3
bears/guards, a witch, 3 bears/guards, I had one more witch just as wall broke so did not
have to fight her. After defeating chapter, go back and play it again, Lyra will be with
you this time so you can collect the sky iron and lore. You come to a guard with an
ice/snowball behind him. After destroying him, dismiss Iorek and use Pan to dig up sky
iron. Go through checkpoint and use Reveal Secret. Blue glow should appear, enter and go
left. Dismiss Iorek and cross ledges, there is a statute other side to bring him back.
Three guards. Break crate for photogram of Bolvangar. Use Iorek to get back up on ledge
and he will be there for you when you enter the rock/door. Have Iorek go first and kill
the two guards on other side of bridge. When Lyra crosses bridge, there is a lower one so
she can make it across. After getting to where second guard was killed, use reveal secret
and enter. Go right, break crate and sword lore is unlocked. Go back out, continue and
when you come to two snow/ice balls, have Pan break them, one has sky iron, checkpoint
right after it. You come to the wall again and have to break it down and will have
3bears/guards, one witch, the another bear/guard to fight again also. Still missing sky
iron.
