Parallel world

The Primordials lived on earth before the great tear, when the earth was still nothing but a ball of melted rock. They had great cities and a great civilization that lasted for milennia. They were The Deities' priests and became their angels, until the Primordial war in which they fought against The Deities and lost. Now they live in what remained of the Primordial sea, inside of the earth's core. Some of their cities and artifacts can still be seen and found, depicting their relationship with the deities, both initial and latter.   The Titans are a species evolved on earth after the orchestrated collision of proto-planet Theia with proto-planet Earth. The Titans were massive and very powerful, able to use magic in very advanced ways and even started affecting their environments in a much more substantial way. A fight between them broke out over what to do with them and destroyed a large portion of the world before the Supreme Deity intervened and came up with the Great Tear, after which in our world the Titans were left to live until their natural extinction and in the parallel world the Goddess Annihilated them without a second thought. Nowadays the only thing that can still be found of the Titans are their skeletal remains and very few buildings that the Goddess didn't notice and thus didn't destroy completely.
