Man

When Man arrived in Iridia, it signified the end of the Days of Yore. The original inhabitants, including the Elves, Mermen and Dwarfs, soon found that they could not coexist with Man and his many vices: The Elves fled to the forests, the Mermen the oceans and the Dwarfs the mountains. The magical creatures of Iridia, such as the unicorns and griffins, were hunted mercilessly, and relocated in secret to Elixia with the help of the mermen.

Man defined the concept of monarchies and created the four kingdoms: Man created and formalized New Magic, which manipulated the energies of the world for a ‘better quality of life’. Experimentation with magic introduced hybrid races like goblins and trolls and summoned vile creatures from other planes of existence such as demons. Hybrid dragons were created during an infamous series of experiments which created great consternation around Iridia, following which the pure dragons returned to their Slumber beneath the Dur'Grande.
