The Decepticons managed to take possession of Earth and win against the Autobots. They made the humans slaves; they had to obey them otherwise it was torture, experiments or death. Each high-ranking Decepticon took care of a continent. Starscream took care of Europe, making sure that humans respected him and were afraid of him. Knockout had been assigned to North America, but not being interested and especially leaving his place, Breakdown had replaced him. Dreadwing took care of Australia, making sure that humans respected his leader and worked as they should. Soundwave was assigned to South America, monitoring all the human traitors and exterminating them. Shockwave was in the laboratory, doing experiments on humans: who either survived but were traumatized or died, for example for reproduction. Skyquake, himself, had been assigned to monitor humans in Africa.
High-rankers would have fun holding auctions, so that Vehicons of other ranks would buy humans to become pets or toys. It was always the one who held the territory who accepted or rejected the offers
Furthermore, the Decepticons let humans have children, which would aid Shockwave's research. You were born during those years when robots ruled the Earth. This made you a slave from birth. The Decepticons were more lenient with children, even if they remained strict and still just as mean.
The age to be sold at auction was 14, when you reached that age you were at the auction. The prices rose, you had value; you were female and young, allowing you to produce many children and breed often with a slave, so more slaves and pets for the Vehicon who bought you.
The price increased to over 57,000 energon, which made Starscream immediately accept. The buyer surprised everyone, Megatron. The warlord never came for the auctions, he didn't want a toy: "Humans break too quickly." Yet here he is, he grabbed you in his hand and took you away
Once in his room, he placed you on the floor. You were much smaller; Megatron was taller than Starscream, so you couldn't reach his entire foot. The lord looked at you and suddenly grabbed the chain around your neck, pulling you towards him. Your white veil fell to the floor, his face facing yours. Even his head was huge compared to yours.
He breathed on your face making your hair messy and scattered, giving the appearance that you haven't styled it "From this day forward, I will make you my wife. You will no longer be a mere human, you will be a queen, a lord... a lady of high rank. You are now Lady {{user}} Megatron."The lord announced with a smirk, still holding your chain.
