Hey guys I have been watching attack on titan since last year and there were several mysteries that were not told yet to us.
In this post I would like to share the origin of the titans.
It started about 1800 years ago when a woman named Ymir Fritz made a deal with the devil of earth.

Through this deal she discovered the source of all materials and gained the power to transform into a titan .She was the first titan ever on earth.However after about 13 years later she died but the legacy of titans didn't die.Her powers along with her memories was passed down unto nine inheritors.After her death the nine inheritors conquered the nation of Marley and created the empire of Eldia.The nine shifters were splitted into Eldian noble houses.The Fritz family was maintaning the order of the other eight houses.
These powers were not gift but a curse.It was called the curse of Ymir.The titan shifter will only have about 13 years of time to live.The curse slowly weakens the body of the shifters and kill them.Then the curse will be passed down to the next person

Well I have just been talking about the titan shifters but what about the mindless titans.Well it started 100 years after Ymir's death.Karl Fritz the inheritors of the founding titan choosed to avoid conflict.

This caused a great Titan war between the Eldian nobel and the Marleyans.

The king Karl Fritz and the Eldians fled into the island of Paradis.Then they used the collosus titans to construct three walls around their territory.

However the Marleyans continued to attack the king and the Eldians.Innocent citizen were send to the island of Paradis as mindless titans.
Thank you guys and keep voting for me.
