For thousands of years, the elemental wizards, sorcerers and humans lived in peace. There were many different kingdoms and tribes among them. But one day, the sorcerers grew angry with the humans. They wanted to become the rulers of the whole earth. They captured hundreds of humans, turning them into man eating monsters, known as the titans. The wizards who saw the wrong they were doing, tried to stop the titans. But the sorcerers knew this was going to happen, and enfused them with a spell that would absorb the power of the first element that get used against them, and posses that power. So were the Titan Elementals born. But among the normal brainless titans, there were nine types of special titans of each different elemental titan.
The Elements:
Fire, Earth, Water, Lightning, Ice, Speed, Amber, Smoke, Invisibility, Shadow, Metal, Poison, Nature
(These are all im gonna work with cause im to lazy to google the rest and i dont remember them all XD)
The Nine Titans:
Attack titan, Beast titan, Collosal titan, Armored titan, Cart titan, Female Titan, Jaw titan, and lastly, the Warhammer titan.
So as the rest of humanity was forced to hide inside walls, created be the titans themselves.
The three walls:
The outermost wall:
Wall Maria, and with it came Shiganshina Destrict.
The middle wall:
Wall Rose, and with it came Trost District.
The wall in the middle:
Wall Sina
