Back in Pagan times, during Baltic-Slavic period out of history books, there actually were only Baltic people. Slavs didn't exist as such.

One night, a young woman accidentaly slept with her long lost father whom she personally didn't know about. Through acquaintances she later figured out the truth about her father, but it was way too late to change a thing. Just about two months later she gave a birth to twins, a son and a daughter. When the villagers found out about this incident, the family got banished without a second thought.

They traveled from village to village, but never could escape the truth, shame kept following them. Father couldn't stand this, he drank the very last coin the family could put together and after just another humiliating lose in a brawl, he commited a suicide, soon followed by mother.

Children were left alone, living in woods like savages, surving through thievery and murder. None would accept them, none would love them. They promised themselves to avenge their parents, to gain a revenge over Balts and so they traveled to a far unhabited land where they made their own village and fucking fucked together and making dozens of children. Through centuries they paired with their own siblings, children, parents and made tens of thousands of warriors, fucking inbreds known as Slavs today.
