Gaining access to the linking book to Voltaic means discovering the purpose of the colored posts you have likely passed time and time again during your exploration of J'nanin. Before we discuss the colored posts, you must first locate the start of the puzzle--a light source just off of the island.
To reach the light source, head right from the top of the dome until you reach the yellow colored post. Turn left and spot the wheel and lens at the edge of the cliff. Approach the wheel; spot the structure--the light source--in the water.
Your task is to rotate the wheel until the light source diverts sunlight toward the lens to the left of the wheel. Keep adjusting the wheel until you spot light beaming from the light source toward the lens next to your position. The lens then diverts the light toward the yellow colored post you passed a moment ago.
The colored posts are in fact light reflectors. You must align all of the colored posts correctly to divert the light from the light source all the way to the tusk door containing the Voltaic linking book. The easiest way to solve the puzzle is by starting at the light source and working your way through the reflectors all the way to the door.
You can gain a big hint to the puzzle by looking through the colored posts. Take note on what you can see through the post lens in each of its three positions. When diverting the light, look through the lens to ensure that the light is pointed toward the desired colored post.
There's another piece of the puzzle once you reach the tusk door. You should keep track of the colored posts, in the order that the light moves through them. You'll need this sequence once you reach the door.
Here's the order of reflecting light:
1. The light source diverts the light to the lens to the left of the wheel.
2. The lens diverts light to the yellow colored reflector post.
3. Adjust the yellow reflector post and divert the light toward the blue reflector post to the right (if facing toward the yellow post and away from the light source). First color: yellow.
4. Approach the blue reflector post.
5. Adjust the blue reflector post and divert the light toward the green reflector post across the center of J'nanin (it's above the greenhouse and creature area). After diverting the light, peer through the lens to make sure that it's positioned correctly. Second color: blue.
6. Cross the map to the green reflector post above the greenhouse.
7. Adjust the green reflector post once and divert the light toward the nearby red reflector post (to the right if facing away from the blue post but toward the green post). Third color: green.
8. Approach the red reflector post.
9. Adjust the red reflector post twice and divert the light toward a second yellow reflector post (not the yellow post near the light source but the second yellow reflector post located across the Edanna tusk and close to this red post). Fourth color: red.
10. Approach the second yellow reflector post.
11. Adjust the second yellow reflector post twice and divert light toward the nearby purple reflector post (to the right if facing toward the yellow reflector post and out to sea). Fifth color: yellow.
12. Approach the purple reflector post.
13. Adjust the purple reflector post once and divert light toward the nearby second red reflector post (near the J'nanin start position). Once again it is located to the right, if you were facing the purple reflector post and out to sea. Sixth color: purple.
14. Approach the second red reflector post.
15. Adjust the second red reflector post once and divert light toward the Voltaic tusk door. Seventh color: red.
16. From the second red reflector post, walk along the path on the beach beyond the light source and the broken post, until you reach the Voltaic tusk door. Note the lens and prism just in front of the door. If you have aligned the reflectors correctly, the prism shines brightly on the door revealing a code panel.
 The aligned colored posts end at a prism in front of the door leading to the Voltaic linking book. |
To open the door, you must enter a correct button sequence. Each button rests within a specific color. The button--or color--order corresponds to the order in which the light traveled through the reflectors. To open the door, press the following button (color) sequence: yellow, blue, green, red, yellow, purple, red.
Enter the room and spot the sphere console, similar to the console surrounding the telescopes inside the dome. Adjust the spheres to match the code discovered inside the dome to gain access to the Voltaic linking book.
