Azaroth
This Goddess of the Sun, destroying a God already. She would be a fine challenge no doubt. But first, I must be more powerful. Rampant destruction, whilst great fun, won't cut it. No, a proper following is what is needed.
"Orobos, send these humans to their city. I do not care how you do it. They will all witness my power, and they will throw themselves at my feet." I commanded.
"As you will, my lord." And with that, my servant vanished.
Doing the same on the other side of the city, the humans were soon gathered behind their walls. With a thundercrash, a flash of blinding light, and the heat of an inferno, Azaroth appeared amongst them.
Orobos then speaks, "Behold, mortals! Look upon your King! Azaroth the Destroyer commans you to kneel!"
Hesitant at first, the sea of humans knelt before their master. However, not all of them were so sensible.
"I will not kneel!" Exclaimed one man, a noble evidentally, by his slightly nicer clothing and the small of entourage of armed men standing around him.
"And who are you, little one?" boomed the voice of Azaroth.
"I am Morgar, king of this land. And I shall not permit your existance!"
"Well, king Morgar, it is only fair that you fight for your crown. You and your men, defend yourselves!"
Both Azaroth and Orobos will go to the settlements surrounding a nearby city, and force them all to go to it. Preferably without too much destruction. Once that is done, Azaroth will materialise in the center of the city, and declare himself God-King. Any one who refuses is offered a choice. Death, or to fight Azaroth. They are all permitted to fight together though, it's only fair.
