The Magmoor Caverns are, as a whole, long and narrow. There are only a few very large rooms, and most of it is subterranean, only three rooms being above the surface. Most of its rooms are superhot, and thus, Samus needs the temperature protection offered by the Varia Suit to traverse through them safely. The magma found here is extremely dangerous, and if Samus falls in, it will harm her, regardless of her current suit. A minor Space Pirate base resides here, with a small amount of technology present in other areas, such as the Flame jet.
