Gods walked on the planet Lamda, guiding the 3 races (Human, Elf, Dwarf) and everything was peaceful. Then Guduranis came. A Demon King who invaded from another world 100,000 years ago along side an army of evil gods and monsters. The people and even Gods of this era where not prepared. The people where especially too weak to contend with monsters. The Gods created the "Status" System for this reason. Guduranis however hijacked this system thus giving monsters "Rank". The Gods then summoned "Champions" from (modern) Earth into Lamda of 100,000 years ago.
Not all the "Champions" where specialized with fighting though. Some of them where better with making weapons/technology to fight. Zakart (chosen by Vida) also managed to get a number of "Evil" (invader) Gods to switch sides, since Guduranis ruled by fear alone. He also wanted to build nuclear weapons to kill Guduranis, which lead to a split. The "Champion" Bellwood (chosen by Alda) was on Earth what you would call an Eco-terrorist. He was fundamentally opposed to spreading technology to Lamda but nuclear weapons most of all. He lead the other "champions" to abandon the 4 "creative" ones. Guduranis did not miss that chance, and attacked the 4. Guduranis could do something beyond mere killing - he can destroy souls (something even the gods cannot do). He shattered the souls of the 4 creative champions.
Guduranis was eventually defeated by Bellwood, but could not be killed. He was chopped into many pieces, and those pieces where sealed. They all remain quite dangerous. If they get into a host, they try to take it over. A host can however use those fragments to wield incredible powers, but doing so increases the level of corruption. It will eventually take you over and rampage (to reunite the body). The only person who had the power to permanently end such a threat was ironically... Guduranis himself. He was defeated but... the survivors of the world numbered only a few thousand.
In order to rebuild the world more quickly, Vida bred with many things including "evil" gods that had changed sides, and in doing so created many new races. She also created a new transmigration system (copied from Guduranis's own). Alda was outraged by the transmigration system, and Bellwood decided the world needed to be restored to as it was before the invasion (a world he never saw BTW), which in effect means the banning of technology and genocide of all Vida's new races. This mass genocide is also necessary to shut down Vida's transmigration system. Alda'a faction launched a surprise attack on Vida's faction (including the "evil" gods Zakart had managed to pull over), thus resulting in a Civil War of the Gods. Alda was successful, and Vida was impaled by his "piles of law" unable to recover. Vida did manage to create a great mountain range to stop the advance upon the lands of her new races. And a great barrier was erected to seal out any Gods who wanted to invade within it, maintained by the gods (some "evil") within it. Alda's faction has ruled the world ever since.
Broken souls cause problems for Rodcorte's reincarnation system, so he slapped the broken pieces of those champions together into 1 soul, and sent it to Earth. There did not seem to be any abnormalities according to him. Rodcorte (being eternally incompetent) didn't notice that soul when it appeared before him again 100,000 years later. When a ship sank, and he sent the victims to Origin with cheat abilities. Except one... the soul of 4 champions got no powers nor fate. When he was killed in Origin, Rodcorte cursed him, sent him to Lamda with the fate of not recovering his memories, living a miserable life, and eventual suicide. However the mostly sleeping/sealed Vida recognized that soul, and intervened. She pulled him into her own transmigration system, and he was born as a Dampire to a loving mother. Vida could not remove Rodcorte's curses, but did what little she could given her poor condition.
