Uthulians

''"They say that every time one was born, the sea level would rise." ''- Person Quoted

Uthulians were ancient, gargantuan sea creatures now believed to be extinct. Thought to have ruled the oceans during the late Primordium epoch, they were the largest known creatures to have ever lived. Present day Otaru trace their own lineage back to these great leviathans, and their city Vyssus Mar is built inside the huge fossilised seashell of a long-dead Uthulian creature.

Precise details on Uthulians' appearance and behaviours are largely speculative, due to the age and scarcity of their remains, and only a few individual creatures have been identified so far (namely the Arboranth and the Myrmidon). The exact cause of the Uthulians' extinction is also unknown.
