In the past, humanity faced several attacks in a row from the second world. Thousands of monsters that exterminated and killed civilians, hordes of colossal giants that destroyed buildings, and dragons that turned entire cities into dust. All this happened after the two worlds were connected.
Centuries ago, the world was untouched by magic. Until suddenly, everyone had access to this blessing. In the beginning, using these powers was difficult and costly. People were born with one ability or another and stayed with it; over time, scholars began to understand the workings of mana logic, channeling and transforming magic into what is known today.
In the years following the emergence of mana and magic, elves, dwarves, and half-beasts began to be born naturally around the world. Then, with a better understanding of mana, world hunger was exterminated, as magic could be used for food production.
