The Port and Starboard Helms are objects in Metroid Prime Hunters, both found in the Helm Room on the Celestial Archives. Both objects, when scanned, repeat the telepathic thread that brought Samus and six other Bounty Hunters here: "The secret to Ultimate Power lies in the Alimbic Cluster". The Port Helm suggests that this message was sent out from the Helm Room, though potentially did not originate there.
"THE SECRET TO ULTIMATE POWER LIES IN THE ALIMBIC CLUSTER." Author and origin unknown.
