The Lost Child Quest, Indiana Jones and the Great Circle.

Some time after visiting Tongdang's hut to get a breathing device, Gina tells Indy that a child, Sunan's nephew, has disappeared from the village, which triggers the quest “The Missing Child”, Fieldwork Indiana Jones and the Great Circle.

In this side quest, Indy and Gina have to explore a temple in the Wat Si Sawai area to try and find Aran. The temple was used to test warriors, so it will be filled with puzzles, especially pipe puzzles.

The Lost Child Quest, Indiana Jones and the Great Circle.

After starting the quest, follow the marker on the map to the nearest location near the Tongdang Hut to start looking for Aran. Explore the area and continue forward until the Tree House appears. Go up the stairs and lift the wooden plank inside to find a letter from Aran. Now that you know it's somewhere in Wat Si Sawai, head there using the boat or any nearby sign to move quickly.

On arrival at Wat Si Sawai, put on your royal army uniform Indiana Jones and the Great Circle to reach the Khmer Warrior Temple safely, otherwise you will need to sneak and fight your way inside. Once you reach the temple, continue forward until you reach a room with rubble in the middle and hear Aran's voice. He explains that he is stuck and needs help.

Turn left and turn the lever with Gina to open the door. Use the lighter to light the wood and see better. Take the single pipe segment and place it in the pipe slot to make the water flow, thus unlocking the nearby door. Head to another room to find a stuck platform. Aran explains that you have to lift it to get to it.

From the platform, go forward, then turn left and follow the frozen gears to reach another area. Walk up to the fallen beam and climb the top hill on the left. Keep going until a wooden platform appears, which is also part of a giant cog wheel. Quickly jump onto it, then jump to the space ahead. Wait for Gina to cross, then jump down to find another pipe segment puzzle Indiana Jones and the Great Circle.

Here's how to solve it:

• Turn the wheel on the left to activate the water source.
• Take the pipe segment and place it in the pipe slot in front of the closed door, which will open it.
• Go inside to find another semi-circular pipe segment.
• Exit and place the new segment on the ground.
• Take the first segment and place it in the other slot, then take the half circle segment and place it in the first slot facing west.
• Finally, push the giant gear with Gina and pull the lever at the bottom to exit the room.

Now that the platform is up, you need to find Aran.

After completing the puzzle, go left to walk through the activated gears until you reach the tree root. Wait for the cog wheel to turn towards the hole and go through it. Use a combination of jumps and whip swings to reach the large gear that you need to crawl under. Go through the door and pull the lever to help Gina up.

When the next door is closed, Indy and Gina must turn the lever together to open it. Go down the stairs, past the gears, then turn right. Pull the nearby lever to make a bridge and cross it to find a large pipe puzzle. Solve it to meet Aran.

To solve the pipe puzzle, you need to activate the left water source, since the right one is already activated, and find the four pipe segments. First, go up the stairs on the left and turn the lever to activate the left water source.

There are two pipe segments on each side of the room (1) and (3), just climb the stairs on the left and then the right to find them. One is found in a room with a jar of torches nearby (2). The latter is locked behind a locked door (4). To get the latest:

• Place T-shaped pipe segment in the first middle pipe, a slot to the east.
• Place a semicircular pipe segment in the pipe slot near the closed door also to the east.

Once the door opens, grab the last pipe segment to finally solve the puzzle.

At the end of the puzzle, there are three main pipes, each leading to a sewer. Indy must arrange the pipe segments so that all three main pipes pump water into the three drains:

• The first pipe slot in the middle is a T-shaped segment (1).
• The one below it is a segment of a semicircle (3).
• There should be a second half circle (2) on the right side.
• Place a straight pipe segment (4) on the left side.

Just follow the placement shown in the images above.

After the Khmer Pipes puzzle is completed, go through the newly opened door to meet Aran. After a short conversation, follow him into the secret room he discovered to find an ancient relic. Finally, return to Sunan's uncle in the Village and tell him that Aran stayed in the temple to investigate to complete the quest “The Child Who Disappeared”.
