Thoughts coalesce in the Divine Sea. In the infinite chaos, they slam into each other with mighty blows that shatter reality. Eventually, a new being emerges, dragging itself into consciousness and out of the chaos which would destroy it, yet created. From this chaos, new gods are formed. You are part of the newest group, having all dragged yourselves onto the shores of your own sentience. Two beings meet you. They are elder gods, having already led a mortal world to the stars. One stands, in the form of a woman. On her brow is a circlet of the purest silver and in her hands a lyre. The other floats, a terrible presence made of a spiked orb of Black Iron that appears red hot, flames licking the sides from holes where it bellows out. “Welcome,” The musician says, “I am Antae. This is Afraegnu. We will lead you to your world. Are you prepared to go?”
"Yes! Oh us, I have been waiting for this for so long! Being a formless bunch of chaos energy gets so boring after a while." Spoke a bright mass of shimmering colors.
"Speak for yourself, I am quite enjoying my formlessness." Spoke an orb that shifted between dark purple and dark blue.
"Maybe you are, but you were always quite boring." Said a golden shape that changed from one polyhedron into another.
As the formless young gods devolved into bickering, the flaming iron sphere bellowed "SILENCE, INSOLENT YOUTHS!", his flames growing into a pillar of fire to emphasize his statement.
"Don't worry Afraegnu, they all start this way." the musician replied, then turned towards the group: "Anyways, we had better get moving, you have a world to take, and primordials to kill."
As Afraegnu lit the way through the void between worlds, Antae explained: "Each one of you will claim some aspect of your world as your domain and create an avatar to interact with it. Before you can get started with creating mortals though, you must slay the great primordial monsters already dwelling there, if you don’t, they will swiftly end any race you attempt to create. There isn't really a best way to do it, if you can fight, fight, if you can trick, trick. Or if you can bind them to your will somehow, do it, just make sure they aren't a threat. However, even after you deal with the primordials, you must remain vigilant. Demons may come to claim the souls of your mortals eventually, it is likely that it will take them a while before noticing your world, but you must prepare for it."
After a while, you arrive into your new world. Below you is a massive blue and green sphere. All over it Primordials battle. Among them, Dragons battle Titans for control of the mountains, mighty Leviathans fight beneath the waves and the Storm Lord claims the sky above them, the Rat Clans fight brutal wars among themselves in the forests, and the Frost Wolf hunts them all.
Antae and Afraegnu depart and the new gods form into their avatars and fly off to claim the world from the primordials, a knight in golden armor, what looked like a living rainbow, an otherwise unremarkable humanoid with an obsidian skull for a face, and many others flew out. Who are you, what is your domain, your avatar, and what primordial do you seek to slay?
