Zeikke "Possesto" Sieghart

Zeikke Sieghart is a boy of ambition but a boy with a corrupted soul. He and his poltergeist have a history, and it was not swell. Being born from a small branch of the Sieghart bloodline, he was less known and without nobility. His ancestor, Derick Sieghart, was exiled from the family but continued the bloodline, forming his own branch. By the time the branch reached Zeikke's generation, it had become incognito. Though unlike most Sieghart, his family trained in form of sword-and-magic styles, making them Spell Knights. Zeikke, by 10, had breached the boundaries of curiosity when he discovered his family hid something. In a hidden cellar, there was a crystal in the shape of a heart. It flowed with dark aura and even being in the vicinity of it caused a sort of corruption in his heart.

Upon placing his hand on the crystal, it reacted to the boy's mana, disintegrating and infusing whatever spirit was trapped within. This spirit was none other than the poltergeist Possesto. His parents, the next day, did not know about the previous night's events due to not being home at the time. Once they looked at a now ill Zeikke, they wondered what had happened. Healers were hired to inspect him, but none could rid the sickness the boy had. Eventually, he woke up one morning and felt rejuvenated completely, the sickness now banished. When an inspection from his parents finished, he left for the woods for monster hunting. During this time, he had suddenly felt a large, searing pain that sprinted throughout his body. First, there was a numbness; second, there was the loss of consciousness; and lastly, there was a black-out. During the black-out he did not realize what happened, but had noticed he was somewhere else; he was deeper in the forest. He was only allowed to hunt a kilometer into the forest, but anything further and he would be punished. Whilst trying to navigate home, he had been forced to run several times from trolls for he was trained enough to be capable of fighting them. There was a point in time during this that he had found several dead carcasses of monsters, wondering if it was him.

At the tip of the night, Zeikke found his way back home only to be met by his parents who had already assumed the following: he went too deep. They scorned him and even prevented him from hunting for several weeks. A year after the black-out, he had discovered who it was and how to gain consciousness of the possessions. Possesto had been a demon who's corrupted soul was seperated from the demonic cadaver only to be forever sealed within the Heart of Eons. The Heart of Eons, before it destroyed itself, had kept the soul bound to its crystal structure, though anything that touches it directly is instantly infused with Possesto, the two souls would then intertwine and bind to each other within a decade. Once he learned of this, he kept reading out a tome he borrowed from the library, learning that once this occurs, then he would become fully controlled by Possesto. For the next several years, he would vigorously train and fend off the poltergeist; though the poltergeist never failed in possession. After the several years of training, Zeikke planned on joining the Grand Chase Knights or the Runic Knights, but was unsure on which to join.

The grudge Possesto holds against Ercnard Sieghart is one that formed before the immortal's disappearance. Possesto once possessed a sibling, whom he knew as Anjel. Anjel had been a demon of deception, considered to be the Chiral Angel in Hell. The two had followed Gardosen, the ruler of hell, then and had fought on the surface in Bermesiah. They had been loyal, skilled demons then but upon battling Ercnard, his brother Anjel was slain and he was sealed within the Heart of Eons by a battle mage. Possesto, living in Hell, had no concept of time and no concept of memory. Once he exited Hell his memory was active and his concept of time followed. To him this was strange only due to the fact that the sudden change in motor skills had occurred. After centuries of being concealed within the Heart of Eons, Zeikke had come upon it, linking the two; although the link would not be complete until a decade from then. Upon the first possession, Possesto learned of his new manifestation, a jester that wielded his old powers but at a fraction of what they were.

Possesto slaughtered many monsters, traveling deep into the forest and breaking one of few rules Zeikke's parents enforce when it comes to hunting. Afterwards he had contemplated his revenge and had possessed his host several times to shape it into something that feels as if it is the norm.
