Swells-Titan

The Swells-Titan is a legendary, bio-organic behemoth that inhabits the deepest reaches of the Broad Swells. It is so massive that entire schools of Hippocampi can swim within its gill-slits, and its arrival is preceded by a localized "Aether-Storm" caused by its immense magical resonance. The Titan is not a mere beast, but a living relic of the Age of Myth, said to have been created by the First Brood to act as a guardian of the world’s oceans.

Its body is covered in a series of ancient, glowing runes that pulse with a steady, blue light, and it is capable of manipulating the very Aetheric currents of the sea to create massive whirlpools or calm the most violent of storms.

Secret Motivation: The Swells-Titan is not actually a single entity, but a biological "vessel" controlled by a collective of Ancient Aether-Spirits. These spirits are the guardians of a "Great Anchor Stone" hidden deep within the Titan’s heart. They seek to use the Titan to protect the stone from the "parasitic" extraction efforts of the Kigum Arcanists and the Steamfort miners.

Adventure Hook: A series of massive, unexplained "Tidal Waves" has begun to devastate the shipping lanes of the Broad Swells. The Gilded Corsairs hire the party to investigate the source, believing that a rival pirate fleet has discovered a way to control the legendary Swells-Titan.
