Ogrimus, Death Rat Horde Summoned

Ogrimus, Death Rat Horde Slain

Upon breath of night, under the darkest moon, by the mountains side, in the valleys deep, lie in wait, the pits of wrath. Where the dark horde breeds, count the days, for their release upon the world signals the conquest eternal.

You arrive at the edge of a swampy marsh. The wildlife has wilted and a horrendous stench chokes the air. You leave your horse at the swamp's edge and wade through a mess of filth. Something sends ripples across the surface of the water. Dark forms wriggle though the muddy shores and their beady eyes peer across the distance at you.

A disembodied voice rasps, “Sleep well, for you were already dead the moment you entered my lair!”

Suddenly your body is wracked with a sharp sickness threatening to drop you below the boggy waters. The world begins to spin as you fight back the poison in your system.

“No!”, coughs the voice. “You fight against your fate! Friends let us help him!”

The bearer of pestilence, Ogrimus, appears from beneath the waters. His festering pustules spew forth a thick green liquid. His chitterling brood surface from beneath the waters.

You fight to cross the mire and slay the patriarch but with each step, you are drawn deeper into the bog. You slip under the waters. Ogrimus can be heard coughing up blood and bile, odiously laughing at your defeat. The waters blind your senses but you know what you must do. You find a hidden strength to pull yourself though the murky waters. Your opponent is caught off guard when you rise from beneath the bog with sword drawn to the sky. His corrupt frail body falls apart with one strike from your sword.
