Synopsis:
The world is just beginning, and you have just awoken. Around you is the nothingness, and in your hands is existence itself. You are existence itself, as is your fellow others. So go forth and birth all that will be in this world.

Essential you are a god and you create or destroy anything you please. A mythos/ world building exercise.

Example:
Throrora - Her whistle reverberates into space and shakes the clouds of formlessness into solid chunks.
Amberom- With their mighty hands they crush the pieces together and set them a light.

Gameplay:
There isn't much in the way of plot or setting. I imagine it would be a sandbox like rp, full of poetically impossible descriptions, limitless power and most importantly being the myth and legends that will one day circulate the world. In the very end of the rp, when enough has been created I think I'll write short summaries about what each character has made (or destroyed) and what they are known for eternally.

It'd be very casual and simple, you could play lots of different gods if you like, and it wouldn't have to follow any real rules. I think it'd be interesting to make a timeline of things created or major events, not in years but in relative sequence.
