The levitation machine or levitator is a Blue Eco device created by the Blue Sage to lift the boulder blocking the pathway to Klaww in The Precursor Legacy. Like any device seen in The Precursor Legacy, it uses power cells as its main power source. It is unknown just how long it took the Blue Sage to build, but one may guess it was somewhat fast due to the boulder only having recently been thrown down.
The machine could also possibly have other uses but it is never used for anything other than lifting the flaming boulder. There's a smaller version in the Blue Sages house, on his ceiling which is possibly the Sage's prototype to the one seen outside.
