The first life to evolve on the world of Miranda began much as lift began on earth (see Abiogenesis). Over 3 billion years ago the very first life was formed in the primordial soup of the world; however life on Miranda evolved very differently from that on earth. At the core of the world lies the heart of Mir, who body is imprisoned in the single stat of the solar system. There is immense power in Mir's heart and while the Earthmother power seals the prison, Mir's power draws power to it.
The power of the Shadow Realms was drawn to Mir and wrapped itself around the prison - isolated from Mir's heart by the Earthmother nonetheless it calls to the power within.
Before the arrival of the True Elves, the world of Miranda was a barren rock. The seeds of life existed on the world in microorganisms, mostly bacterial, but it was contained inside one of the seven loci that formed the outer bars of the prison. The True Elves changed everything when they arrived. They created Sylvan Vales across the world that formed new loci.
Inside of these new vales life began to multiple and get more complex. Oversaw by the True Elves, life spread and multiplied across the world. The elves did not change or guide this life, but instead saw themselves simply as the caretakers or watchers as millions of new lifeforms began to evolve.
The godly species are those that were created by the power of the gods when they walked upon the Mortal Plane. Most of the species were created during the Age of the Gods to fight alongside the gods in their war against the devils.
Only one species of life naturally evolved on Miranda, the Sha’rek’ta. However, several unique species did evolve from a evolutionary branch of a common ancestor.
When the magi agreed to their pact with the gods and left this world they demanded as part of the price the right to sow their own seed upon this world - as the gods created their own children. The magi created three species; humans, brund, and the ged-zari.
