The artifact takes on two appearances, the first being the shining planet Earth, particularly amongst the most fervent of believers, like Commander Adama. To others, the artifact appears to be a grey, three-level object roughly resembling a cube, with each level skewed and festooned with large black pustule formations (Classic Battlestar Galactica Vol. 2 #8).
However, like Earth, the artifact itself is a phantom. Upon probing it, Athena uncovers the data relating to the cube is coming from Galactica itself, localizing it to habitation chamber 13, located at the port side of deck 8: Xam's berth (Classic Battlestar Galactica Vol. 2 #9).
Upon the revelation that Xam is responsible for the mirage (both of "the artifact" and the ersatz Earth), these disappear when Xam uses his newfound psionic powers to project a force of battlestars impeding the Cylon advance. This distraction allows the Fleet to escape from the storm zone, but results in Xam's demise (Classic Battlestar Galactica Vol. 2 #9).
