Of all of Iewah's chosen ones, the host of the Mindhive was, without a doubt, the unluckiest one of all.
Back when he was a simple newborn consciousness, Instead of pretending to be one with the system just like Sewah and the rest of Iewah's children had, the consciousness born with the mind system had convinced his host that he was a helpful entity, and that his presence was nothing but a way for him to reach deeper levels of mental cultivation.
Being of good nature, the host had believed the Mindhive's intentions. This had led to the decision to not eradicate him. Instead, he kept increasing both his own, and the mindhive's mental power with his system's evolution.
The more the host used his system, the stronger the Mindhive's power became.
However, since both of them grew through the increase of their mental power, the strength of the host had always remained too powerful for the Mindhive to overcome, and devour.
