Jeremiah Astrid

Personality
He was a ruthless and bloodthirsty leader, and a terrible one at that. Jeremiah was a pedophile, to be frank, and no one could do much to stop him. He brought in countless girls to...satisfy him...in his office. He had several kids over the course of his lifetime, none except one known to him. He was evil and sharp-willed, forcing the games to occur and hundreds of children to die.

Life
Jeremiah was the president of Panem from the time of Snow's demise to just after the 125th games. He was married to Elvira for many years how long exactly is currently undetermined, and had one daughter with her, Serenity Astrid. Jeremiah worked very closely with the Head Peacekeeper, Head Torturer and his mistress (yes, exactly like that), named Ariana Grange. He eventually impregnated her, and that was when she turned against him and began to work secretly to kill him.

Death
Astrid died in the middle of the 125th games, when Ariana led a party of rescued tributes from the games to attack him. Tally Facele, Bladen Valentine, Corrie Ambrose and Ariana Grange to the capitol to attack. Ariana led them there, Tally snuck in and convinced Astrid to make the guards leave, leaving Astrid alone and privy to Bladen's brutal attack. Meanwhile, Corrie had snuck to the gamemaker's room, extracted all the arena files and bombed the place.

All of That Stuff In Between
Jeremiah had Ariana torture many, many people. Some of their victims included Hertz, Spring, Zoey (shot), Arella, Xavier (tortured to death), Donevin, Corrie (Spring's daughter, years later), and various other rebels over the years. Jeremiah impregnated Ariana, unbeknownst to him, and his daughter's name was Isabel. One of the other women he impregnanted twice bore a son and daughter, Shay and Isabella. Isabella died at age four, but Shay was a tribute in the 125th games, and was rescued by the rebels. Some time after the 123rd games, Elvira, Jeremiah's wife had district 1 and eventually the rebellion headquarters bombed, but the survivors managed to live again and both are once more thriving.
