Zacharie is a complicated figure. When he was just four years old, his life consisted of having been abducted with his siblings by three monstrous witches. They did not survive as they were brought into a liminal forest- separate from his homeworld. As the only surviving child, purely due to being favoured by one of the witches, he ended up being adopted by them and was raised with them. He was raised as a warlock, despite lacking magic capabilities, and to this day he still dearly loves his mothers.

At age 16, he was forced to leave the liminal forest. His mothers did not return home from their travels. They told him he had to leave if they did not come back after a day. So, he did. After wandering the woods for a few days, authorities were notified, and he was eventually taken in and reunited with his birthparents.

His life as a human was troublesome, struggling to connect to other humans and in general being very damaged after having to so suddenly leave his mothers, his home, and everything he knew behind. He had no choice but to harshly alter his entire life to fit in with humanity, and nothing good came from it. Years of therapy, various medications, antisocial habits, and intense focus on education as his only activity made him a distant individual. He had given up on connecting to other humans, instead setting his mind on finding some way to return to the forest, or any other location he had visited with his mothers. Any way to get back to a place with magic that made sense to him. Where there were also strange people like him.

His lack of social life made him favorable for an organisation dedicated to hiding and studying the anomalous and "magic" entities from the world. He was hired on, having direct access to many of the entities and objects they stored there. Eventually, he began his operations. First acquiring a tool of knowledge and guidance, a "key". And with that key, he was directed to allow his body to get slain by subject 11, and trade his body for a part of its magic.

Nowadays he lives as a Warlock, using his profession as a name as well. He is chaotic, fun-loving, and exciteable. He is dedicated to the work he performs and treats it with utmost care. He was willing to give up his own eyes and many of his own emotions in order to be able to create a world for his friends, where they could all have fun.
