Take all the time you want bringing me the Precursor orbs, I'm not looking to fix the pontoon bridge anytime soon.”— Warrior, The Precursor Legacy
Bring 90 orbs to the Warrior was a mission in The Precursor Legacy that Jak and Daxter completed to obtain a power cell. After being defeated by Klaww, the Warrior took the pontoon bridge apart, blocking the way to Mountain Pass. He restored it after being brought ninety Precursor orbs by Jak.
After collecting at least ninety Precursor orbs, you can trade them for a power cell, and the Warrior will reassemble the pontoon bridge, giving you easier access to Mountain Pass and Boggy Swamp. The Warrior is located in the pavilion in Rock Village.
Note that this mission is not necessary to gain access to the Mountain Pass and Boggy Swamp as it is implied, as with quick feet and good timing Jak can jump across to the second pontoon anyway.
