.. Getting to the Eastern Courtyard

From a lever, like all of them. ( The lever is on the same wall, a little bit higher. )

Now, Tove could climb up there and pull the lever.

There's a frozen crack. She can't get hold of it.

You could help her climb it. If she just would have some climbing gear.

Oh yeah. There was this box of climbing gear behind the bear statue, at the first gate.

Henrik can use the piton on the crack to make it easier for Tove to climb.

Oh, get some helping tool. ( There is a hammer in the dungeon. Henrik must take it. )

Now, Henrik must hammer the piton into the crack. Tove climbs up and pulls the lever and the portcullis opens. You can now enter the Eastern Courtyard.
