ONEof the world's most prosperous countries is hailed asEastre Vallera. Two centuries ago, an unprecedented agreement was made to ensure the peaceful coexistence of humans and sorcerers. These accords began in the northern and southern regions of theLand of Ceandosand gradually spread to the rest of the eastern nations and beyond.

Gifted with the ability to harness and control magical forces, sorcerers are believed to possess a unique genetic makeup—a divine blessing from a higher power. Nonetheless, despite their extraordinary abilities, they are still human.

Ordinary people were not always accepting of sorcerers, once forbidding them from walking the same ground in their world. This likely stemmed from fear and a sense of threat towards their unique abilities. However, the ancestors of sorcerers demonstrated their good intentions and dispelled any doubts of their kind.

The acceptance brings with it the reality that others with less benevolent intentions reside among them, presenting a potential threat to both sorcerers and humans. This requires them to navigate a world where not everyone values the same peaceful existence.

In a world where both beings coexist, the justice system works differently for each group. When an ordinary person commits a crime, they are subject to the justice system of their society, with authorities enforcing human laws. However, when a supernatural being violates the law, a select group of their kind must deal with them.

Comprising skilled sorcerers who utilize their expertise and powers to investigate and solve cases involving beyond-natural incidents and beings, an organization was established by theCouncil of Sorcerer's Affairs, their governing authority. These groups, created to safeguard the general public from emerging threats throughout the country, are known as theSorcerer's Leagues.
