Yeesha's bookshelf has 16 books that have names written in D'ni. In Yeesha's Journal and in the lower garden in the first hut in Tomahna (shown left) when the light is shone on the wall, has the family tree of Atrus's family.

Near Yeesha's room is a book that translates D'ni (shown right)

You can move the cannonballs and one of the boxes. There is a counterweight system in place.

Move the box out of the interior. Place cannonballs into this until two are left outside of the box. Move the box into the interior. Find the other box. Put cannonballs in it until only one is remaining outside the box.

Pull the lever and when you reach the top move the box onto the walkway.

At the end of the swamp, you'll find a bridge. Up high is a lever and if you pull it it will reveal the bridge puzzle.

In Achenars Journal it gives a list of animals. Throughout Haven there are totem poles that have animals near them. The order of this puzzle is by the animals. One of them is blocked, but you can figure out which one it is by using the bones next to them.

Find and take pictures of the four mangree sketches in the lakehouse (1 in desk, 2 inside chest, 3 on table upstairs, 4 behind painting upstairs)

Your goal from the south forrest (picture left) is to get the Camoudile to fall in the pit and get the all white Mangree to be in the left most tree and hit him with a fruit. To do that turn the 3 wheels in the following order:

W1 turn .5; W3 turn 1.5
W3 turn 1.5; W2 turn .5
W1 turn .5; W3 turn 1.5
W1 turn 1.5; W2 turn 1.5
W2 turn .5; W1 turn .5
W1 turn .5; W3 turn 1.5
W3 turn 1.5; W2 turn .5
W1 turn 1.5; W2 turn 1.5
W3 turn 1.5; W2 turn .5
W1 turn .5; W3 turn 1.5
W3 turn 1.5; W1 turn .5; W2 turn .5 (and do it quickly)

Now head down to the forest.
