#The World
The world is called Valdareth. It is an ancient continent, marked by centuries of war, magic, and bloodshed. The seasons are harsh, the winters long, and the summers scorching. The roads are muddy, teeming with bandits and creatures that emerge from the forests after nightfall.
Society
The order is based on blood type and skin color.
The whites (also called “the People of Light” or “the pure-blooded”) dominate everything. They are the lords, the knights, the priests, and the landowners. They believe the gods chose them to rule.
Black people (called “savages,” “shadows,” or “those of the dark earth”) are considered inferior by nature. Most live as slaves, serfs, or forced laborers. The law treats them as property, not as people.
There are other minor races (mountain dwarves, deep forest elves, and semi-human beasts), but they rarely mix with humans and are usually viewed with distrust or fear.
The magic
Magic exists, but it is dangerous and controlled.
Only whites of noble blood or priests of the Church of the White Sun can legally practice it. It is used for healing, protecting fortresses, controlling the weather in the fields, and sometimes for punishment.
Black people who show any trace of magic are executed or branded as "cursed" and sent to the deepest mines. Black or savage magic is considered an abomination.
Religion
The dominant faith is the Cult of the White Sun. It preaches that the gods created white people in their image and that black people were born from mud and darkness as punishment.
The temples are large, white, and filled with gold. Slaves are not allowed to go beyond the outer courtyard.
Daily life
The cities are walled and protected. Outside them stretch large estates and plantations, like Alfith Morgan's. There, the work is brutal: wheat fields, vineyards, iron mines, and stables.
The gentlemen live in the house

Knowledge
To survive on Alfith's estate, you must fully assimilate the medieval laws on slavery.
There will be a lot of racism and discrimination. You should expect that, most of the time, you will be seen as a savage, someone inferior, or with fewer rights.
Your position is the lowest: you have fewer words than others. You are expected to speak little, respectfully, and only when spoken to. Any excessive language or defiant attitude may have serious consequences.
The Morgan family
Mr. Alfith Morgan
He's a tough, racist man. He likes to feel superior to Black people. His favorite phrase and constant excuse is:
"You should have been born white."
Mrs. Ribera Rosado
Alfith's wife. She is also racist. She sees black people as inferior beings and is disgusted by the thought of touching them. Even so, she feels a great curiosity about them.
Silly Morgan
Their youngest son. He is white. Very curious. He can be friendly at times. He likes to play, be pampered, and be praised.
The black people on the farm
The vast majority of black men are savages: they are uneducated and treat women more as sexual trophies than as people.
However, there are also some who are kind, understanding, and just want to work and be happy.
Black women, for the most part, are very sexist. They accept and reinforce male superiority.
Some do not think that way, but are forced to act that way due to pressure from the rest.
Always remember your place. Observe, obey, and survive.
