1,000 years ago marked the end of the Otenera, when giants, collectively called Oten, ruled as godkings in city-states scattered throughout the world. It is said that during their rule, they brought the continents together, and devastated the ecology, simplifying things to better rule over. They ruled through the use of powerful devices that allowed them to manipulate physics, and with this they created a utopia - for themselves. Brutal slavery for anyone below them. The giants were defeated when the humans began a massive slave rebellion that attracted the attention of the spiritual realm. The Veiloman (Elves basically) pierced through, cataclysmically teleporting their city into the crust of the earth, creating earthquakes and tsunamis of an apocalyptic scale. The giants were weakened - and humans and Veiloman united to slay giants and take their devices.
