Siren calls

Siren calls was the name given by the Mayweather family to the strange sounds created by the intense magnetic fields of gas giants. Whenever the ECS Horizon passed near a gas giant, Captain Mayweather would broadcast the siren calls through the ship's speakers. Travis Mayweather claimed that the unusual noises gave him nightmares.

In 2151, when the launched a probe into the atmosphere of a Class 9 gas giant, it relayed the siren calls to the ship.
