The Fey Being

The Fey Being was a member of an advanced race that landed on Earth roughly two thousand years ago. It is the source of all Essence on Earth.

Appearance
Records of the Fey Being are hazy, but recovered videos of it reveal it to be a large, semi-mechanical monster around the size of a large ocean carrier. It had a salamander-like body, except it seemed intertwined with pieces of metal and machinery.

History
The Fey Being seemed to rest inside the moon for an unknown amount of time. Once colonization began on the moon, and with that excavations and drilling, it woke. It slammed down onto the Earth, around the then Baltic Sea. It began a war path of destruction, and quickly destroyed country after country. After destroying much of the world, the attacks of several powerful nations seemed to damage it. It carved itself into the crust to heal, but died of its wounds. Since then, the Essence that made up most of its body rotted off and circulated through the Earth's crust throughout the entire world.

Since then, the Fey Being has been revered, investigated, or shoved into the corners of people's minds. It's argued whether or not Essence's birth-limiting effect is owed to the Fey Being, or simply a by product of Essence itself.

Large Essence Reserves
The Fey Being has the most Essence ever gathered by one being, and could use abilities seemingly endlessly.

Essence Mastery
The Fey Being had complete control over Essence, and used it generate large beams or shock-waves that decimated cities.
