Anankos is the main antagonist and the true final boss of Fire Emblem Fates. He is also responsible for creating an impostor Garon and possessing Takumi in both Birthright and Conquest. Once revered as one of the First Dragons, his degeneration resulted in the obliteration of both Valla and almost all of its people. Anankos is one of the First Dragons, also known as the Silent Dragon and the Dragon of Wisdom. Anankos loved humanity and gave them longevity and knowledge. Anankos became particularly close to the kingdom of Valla and started to live among its inhabitants. He was also a particularly close friend of Cadros, the first king of Valla. To a select few, he gave the essence of his blood, allowing them to utilize the power of Dragon Veins, a trait that was passed down through the Vallite royal bloodline. However, as with the other First Dragons, he began to degenerate over time. Unlike the other First Dragons, Anankos did not shed his mortal shell, opting to stay behind as a figurehead for the Vallite people. Through the power of a song and a fragment of his dragonstone, both of which were passed down through Vallite royalty, his urges could be quelled. However, after many generations of kings, Anankos's rage grew strong enough for him to burn down a forest. The people of Valla blamed him for it and tried to kill him. Unable to comprehend that the very people he had helped had betrayed him, Anankos locked himself away in a mountain cave, where his detest of humanity grew. The King of Valla and a few select people would make trips to his cave to express their belief in him. Unfortunately, he lost control of himself and killed the King of Valla of that time. Before he completely degenerated, he tore off a portion of his soul, which took on a human appearance in a last bid to stop his rage. Anankos then began to form an invisible army consisting of many of his former Vallite subjects. He even began to resurrect the dead to strengthen his army. He also self-sired a daughter named Lilith to further his goals. The human portion wandered with no memories of his past and soon met Mikoto. The two fell in love and eventually gave birth to a child. However, soon after the birth of his child, he recovered his memories and sent them away from the kingdom to spare them from the ruined kingdom. He made Mikoto promise to never tell their child of their father to spare them from the burden of his past sins. With his newfound clarity, he had a vision of another world where many heroes felled a great dragon. He desired to seek help from the warriors of that world.
