This Novel is presented by @Mangrove_Vibes (Me) as a Fan Fiction of the popular manga "Attack on Titan" written by the honourable Japanese Writer Hajimé Isayama.
As an Attack on Titan fan, I was too much saddened after reading the whole manga. The ending of the manga left a spot as a message from the future or maybe an ending(maybe). I wanted to complete one more round of the cycle of the Titan theory in AOT like... Ymir(The Founder of Titan's) became the first Titan by being attached to a Prehistoric being known as "Hallucigenia"(source of all Life as They say). It was living under an unusually big tree. so after Eren died in the manga, His Severed head was buried under the tree that He use to nap and hangout with Mikasa and Armin. After a lot of time,The tree grows larger and larger to match the tree that Ymir's Hallucigenia lived under. Then a Kid and His pet Dog comes to investigate. That's how the manga ended...
I started the next round of the Founding Titan and Titans from that ending with the help of Time loop and the paths.
