Dolphin

=Overview=
 * Dolphins are the only co-evolutionary species of Man, as both are mammals that are known to have come from the same seed ship. Because of this, when the Naians speak of themselves as the Oceanborn, they include dolphins as well.
 * Known honorifically as the Aún and colloquially as Fins.
 * Aúräna is named after the Aún.
 * Dolphins are highly intelligent and have benefited from many of the same genetic advancements that the Naian ancestors did, including a greater tolerance for pressure than their distant Terran predecessors.
 * Naians and Fins are able to communicate through Trinary, a language of clicks and whistles that most can use to convey immediately simple ideas such as 'Help' or 'Danger'. However, almost every Naian or Syren pod has at least one member that seeks to master its every nuance, allowing for far more complex understanding.
 * Among the Naians and Syrens, a pod that lacks a Fin member is considered something of a joke and not really a pod, owing to how vastly less effective they are. Naians have the closest understanding of their dolphin podmates, yet Syrens are more alike in temperment.
 * There are exceedingly few Mantean pods that have Fin members, owing to the dolphin's aversion to the Abyss - and some dislike of the Mantean attitude in general.
 * Dolphins are considered more than just an auxillary species by the Naians - sentient brethren that have more in common with their fellow Oceanborn, than with the Surfacers.
 * Surfacers do not recognize Fin sentience, regarding them to be highly trained and dangerous animals.
