On Dragonhead Isle, you discover an ancient relic, and receive a message guiding you to a new destination.

Take the Relic

Pick up the relic and you will carry it above you. Go down the ramp with it, then set it down near the Wings. Use the Device Dispenser if you wish.

Attach three fans and a rocket to the back of a wing, then attach a steering stick, and finally, attach the mask to the front of the wing. Then get on the wing and use the controls. Fly it to where the beam of light is pointing. Make sure not to lose the mask, or you will have to go back for it. When you have reached the location that the beam of light is pointing to, detach the mask from the wing and carry it to where the beam of light is shining.

After the cutscene, carry the mask to where the beam of light is now shining. Set the mask down on the platform that you find. There will be a cutscene.

Go south and activate the nearby lightroot. Then go back north and take the mask, and carry it to where the beam of light is shining. This is the Construct Factory.
