To enter the temple, use the Force to open the main doors. Inside, use the Force on a broken pillar to form steps leading up to a higher floor. To open the locked door ahead, use the Force to pull off two broken pillars in front of the door, exposing two switches. Then, use the Force on the switches to open the door. At the large semicircular chamber, check out the three short corridors on the right side. Use the Force to extend the platforms, and use them to reach the levers. After flipping all three levers in these short corridors, enter the central doorway that opens up. To complete this chapter, use the Force on the holographic projector.

Canister Locations

Canister 1: The canister is lying in the open, along the temple's front walls. From the main doors, head towards the left of the screen to find it.

Canister 2: From the temple's main doors, head towards the right of the screen, and grapple up to the rock ledges. Climb to the top of the main doors. The canister is behind the windows.

Canister 3: From the temple's main doors, move towards the camera, over to the crumbling ledges. Use the Force on three large block pieces to stack them up. Double jump (as Jar Jar) up from them to get the canister high up above them.

Canister 4: Inside the temple, use the Force on a broken pillar to form steps leading up to a higher floor. On this higher floor, go through the narrow doorway to enter the conference room. The canister is on the large circular display.

Canister 5: Before going through the door that leads on to the large semicircular chamber, follow the stairs down towards the council room. Before entering the council room, look past the broken edges of the walkways to the side to find the canister.

Canister 6: Before going through the door that leads on to the large semicircular chamber, follow the stairs down towards the council room. Inside the council room, use the Force to stack up the chairs, and then double jump (as Jar Jar) up along them to reach the canister high up in the center of the room.

Canister 7: In the large semicircular chamber, the canister is above the lever in the first short corridor on the right side. Use the Force to pull out the platforms, and double jump (as Jar Jar) from these platforms to reach it.

Canister 8: In the large semicircular chamber, the canister is above the lever in the rearmost short corridor on the right side. Again, use the Force to pull out the platforms, and double jump (as Jar Jar) from these platforms to reach it.

Canister 9: In the large semicircular chamber, flip all three levers on the right side to lower a mechanical arm (as well as open the door that leads to the final room). Double jump (as Jar Jar) onto the platform on this arm, and from there double jump onto the high ledges that lead around to the left side of the large semicircular chamber. Leap over the force field to enter the rearmost short corridor on the left side. The canister is inside this short corridor. (To shut off the force fields, activate the astromech panel here.)

Canister 10: After shutting off the force fields, flip all three levers on the left side of the large semicircular chamber to raise another mechanical arm. Double jump (as Jar Jar) back up to the high ledges via the first arm. Then, leap over to the platform on the second arm, and from there double jump up to the canister high above.
