The Phendrana Drifts are located on the southwestern edge of the explorable regions of Tallon IV. The area is relatively isolated, being only accessible through the Magmoor Caverns. The Drifts consist mostly of icy canyons and ruins of ancient Chozo buildings, though there is a major Space Pirate outpost near the edge of the region as well.

Despite the cold temperature, many unique species can be found in the region, such as Sheegoths and Ice Burrowers. The Space Pirates' experiments with Phazon have also created an animate rock monster called Thardus. In addition, Meta Ridley's figure can be seen briefly, flying high above the Phendrana Shorelines.
