Helm of the Dark One

Once protecting the skull and cerebreal core of The Dark One, the Ancient Black Dragon known as Gruveir, the enchanted helm fell from the dragon's skull from a pointed shot from Alton's firearms, falling to the floors of the Elysian Institute of Arcana in the midst of battle.

Harrowed in dark energy and demonic power, the helm exudes a never ending green smoke from its shell. Focusing upon the helm and its power, flashes of images, words and symbols appear before the researchers eyes.
Robes adorned, embedded with draconic tokens, dress the individuals that surround you, each chanting words of the abyss, calling about some great entity.
Oscillating around you, crackles of purple lightning, the growing of green mist, the sound of ripping flesh as a rip within planes grows wider and the soul of another is released.
The sounds of chains then ebb and flow through the mind, making the guttural words that follow near incomprehensible.
Child. Awaken. Grow. Conquer. Serve. Unite. Return.
You awaken, runes upon the floor that were once not, etched and emblazoned with necrotic energy, the symbol of a spiralled chain upon the floor beneath your feet.
Devour.
