Gilled Giant

The gilled giant is an unknown species of fish that has been sighted only a few times in Nidus' existence. It has only been sighted in The Outer Rim, and it is the largest species of animal to ever be recorded.

Due to the rarity of this creature, some speculate it even exists. However, locals swear by its existence and several fishermen dedicate their lives to finding this elusive creature.

During the future era, the outlanders hear of the gilled giant's existence and seek it out for its genetic superiority. They believe that if they can harness this creature's powers, they will be able to survive after The Last Soporatus.

In the last moments of Nidus' existence, when most of the ocean has receded and dried up, the outlanders find the gilled giant, breed it, and create a giant space vessel. This ship, known as Spero and spanning nearly 100 kilometers, holds the key to life outside Nidus.
