The planet Tiberius.
A harsh world situated at the very tip of the galaxy's eastern fringe. The closest planet to its sun, it is doused instead by great seas of molten magma that dominate its surface. It's rocky continents are dotted with miles upon miles of treacherous mountain ranges, made ever changing by the brutal winds that swirl within the athmosphere, carving the earth with untamed force. The athmosphere itself was but a cocktail of thick, toxic gases unheard of in the human table of elements, without even the slightest hint of oxygen in the mix.
Needless to say, this planet could not support life on its own. But deep within the subterrenean caverns beneath the raging sea of flame lay a vivid contrast from the surface. Given light by strange crystals embedded into the cavern ceilings, lush jungles teeming with all sorts of life flourished and spread like a living carpet, untouched by any outside force since the birth of the planet. That is of course, until now.
"Burn!" Rang a shrill, distorted voice as a torrent of purple flame tore a flaming swathe across the green jungle canopy, reducing miles upon miles of life into a field of glowing embers and ash. At the borders of the destruction and the untouched jungle, all forms of creatures fled for their lives, predator and prey pushing past each other as a terrible sense of foreboding overcame their primal minds.
At the source of the inferno stood a dark, towering figure, more than three meters in height, the ground around him still glowing with the unholy energies of his arrival. His body was completely encased in heavy and intricately designed armor, a vivid dark blue and gold in color, ornate with runes that shimmered with dark energies. His shoulders were laden with massive pauldrons, and on his head, he wore a great horned helm of gold that revealed only his empty eyes to the world around him. In his left hand, he held a twisted staff of silver coils wrapping around a horned, inhuman skull at it's tip, it's gaping jaw fixed into a scream like impression with hazing smoke coming from it's mouth. In his right hand, he held a great tome which seemed proportional to his size, numerous heavy chains erupting from it's spine and wrapping around his arm, seemingly melding into his armor. Robes of unnaturally pure white cloth billowed from his torso and trailed gracefully behind him as he strode forward with surprising ease, his massive boots crushing anything it stepped on, leaving gigantic foot prints in the barren black ground.
"It is here..." He whispered in his deep distorted voice beneath the helm, as if speaking to beings only he could see. "By the gods, it is here... I can feel it's presence, tasting my soul like a fine wine... It's chilling fist wrapping around my heart and mind..."
He walked for a few meters more, indulging in the sensation before coming to a halt, the chains that bound him to the book gently rattling, echoing in the now silent place.
"Is this what you brought me here for, my master?" There was silence, and the answer came in the form of a raging wind that swirled momentarily around the speaker before dying down instantly. Without further hesitation, he raised his staff to the heavens and said "For You have spoken, so shall it be done..."
Bringing his staff down hard on the charred ground, tendrils of dark energy twisted from the skull's gaping mouth, slithering down the staff before scattering across the earth in all directions like a swarm of ravaging serpents. The ground shook as the swift tendrils raced in all directions finally slamming the walls of the untouched jungles like a black wave. The tendrils advanced further, corrupting all forms of life as they ventured deeper into the jungle with the taint of chaos.
"Look, my Master..." The sorceror whispered once more with barely contained excitement. "As I speak, your Holy influence reaches out to all the souls of this ignorant place... Soon, it will reach that which you seek... That which shall bring this universes Salvation..."
The winds swirled around him once more, longer this time, with greater force that a perfect circle was traced on the ground around him, and Sorceror Lord Antiphameus the Enlightened smiled toothily beneath his helm at his Master's approving response.
"Thank You, my Master... Thank You for this Holiest of blessings..." By this time, the tendrils had entirely covered the subterrenean jungle of this continent, writhing in bundles of dark energy before they tunneled into the rocky walls of the jungle edges, determined to spread all throughout the planet. "Through my soul and body, You shall once more feast upon the souls of this universe..."
Meanwhile, in an altogether different plane of reality, malevolent laughter echoed throughout the immaterium as the dark eyes of a being of immeasurable power watched his pawn enact his millenia old plans.
