Artifact of Elder
The Artifact of Elder is one of twelve artifacts Samus must retrieve from Tallon IV in Metroid Prime. When all twelve artifacts are collected, Samus brings them to the Artifact Temple to open the way to the Impact Crater.
The Artifact of Elder is in the Control Tower in Phendrana Drifts. To acquire this artifact, Samus must melt the ice outside the window of the eastern elevator tower using the Plasma Beam and fire Missiles at the now-exposed fuel cells. Afterward, she can approach the tower that collapses as a result of the explosion and roll through the small passage in Morph Ball mode.
