Ahsa

Sea monsters are giant aquatic sea creatures that resemble serpents and live in the methane oceans of Titan. It is unknown if these creatures were always present on Titan, or if they arose or were introduced to the planet following the onset of the Golden Age. One creature can be seen through the windows surrounding the arcology's CPU core in the Festering Halls during the mission Utopia. Ghost mentions that the arcology's sensors can detect a large object moving under The Rig, and although the sensors can't determine what it is, this is likely the same creature.

Trivia

 * Intiaily, players mistook parts of the Arcology for a Sea monster, much like how in Destiny players thought Batadactyls on Venus were Ahamkara.
