==Guide==
First you need to get to Mirage Tower. If you have been to the tower and solved the puzzle there before, you can fly to 1R253 Scrapyard and take the warp that appears in the house in the bottom left corner.
If you haven't done either of above, take the train to the desert. Go slightly right from the station and go up until you reach a new rail, you can check whether the Mirage Tower Indicator Pole appears. If the Pole appears, the Mirage Tower appears. To get this item, you need the Mirage Tower to appear.
The left image shows the area when the Mirage Tower doesn't appear. The right image shows the same area when the Mirage Tower does.
If it doesn't appear, touch the Light Shards at the oases until the Mirage Tower appears. There are four oases near the arrival station. The two on the first row are to the left of the station, and the two on the second row are to the right.
Once the Indicator Pole appears, go all the way to the top right corner of the desert where the Mirage Tower is. Go inside the tower.
You need to solve the puzzle in the tower to proceed. If you haven't done that before, follow the guide here.
After you have solved the puzzle, go all the way to the fake exit and go down to the bottom exit.
