Backstory
Sometime after the 75th Games, the rebels stormed the Capitol and took over. By the time of the 78th Games, President Alma Coin had gotten bored with just ruling Panem and decided she was going to rule the entire world. Panem's Districts were turned into warring states as they conquered country after country. Even after World War III, some of the Districts kept their fighting nature and do train their tributes even though they aren't as pampered as 1,2 or 4. These "New Careers" are Districts 7, 10 and 11.
Soon, Panem became the entire world. As the number of Districts grew too, a new Hunger Games rule was instilled: Every Continent would have their own Games, to which they will send their Top 4 to the actual Games. Some of the New Districts are Careers too, but that will be up to you dear reader.
Reading of The Quell
Alma Coin stood in the Capitol City Centre, accepting congratulations left right and centre. As if to commemorate the 100th Games, just over a month ago, Panem seized control over District 99 and 100. For sure this year they would be participating in the Games. She smoothed her hair out as she picked up the card. "To remind all the rebels -and newer Districts- that the choice of one could easily determine the fate of all the others, not all Districts will have to participate. Each participating District will send only ONE tribute-" she paused for effect. The people sighing with relief and cheering. A wicked smile curled her lips, "The Victor of the Games will be allowed to pick up to 5 Districts to send extra food for a year too... All non-participating District will not be allowed to take a tesserae for the rest of the year."
HEH. There's your twist, one tribute per District. Which five Districts your tribute will pick, EH WAIT, Tribute submissions NOT OPEN YET. They'll be opened when I finish my other SYOT. Meanwhile, please submit a District, thanks for the quick response guys, you may submit up to 3 Districts. I need some Bloodbath and Career Districts please.
