I am the undead king. I have lived on this earth for many millennium and I have seen the many rising and falling of empires. I have led my army across many battlefields and crossed blades with the greatest warriors to ever walk this earth then place their skull upon my throne as a tribute to their undying mastery of the art of combat. My army is that of the undying sort. Many of the greatest warriors have died fighting me only to be reborn into my army of darkness. There is no force on this earth that can stop my destruction; the devil himself fears me.
My pact with the gods that sealed my fate was worded thus: “From this day forward, I take the burden of the world into my hands. My destiny is now tied into the destiny of every soul in the existence in the past, present, and future of this earth. I take eternal life as consequence of this pact along with the power of necromancy to deal evil through the rest of time. I am hereby declared as the Undead King and my rule shall be forever”
My army of darkness is made of the enemies that have perished under my original army of demons, which have long since gone. Great and small empires and their citizens who have challenged my rule or evilness perish and were consumed into my undead army that spans from here to the gates of Hell where the Devil cowers in fear of my wrath. For his safety the Devil made an agreement to supply me with a demons in trade for souls of my undead soldiers.
