The ritual of receiving a crown from a Devil or an aspirant to be a Devil was simple, but dangerous for the receiving party. The greatest risk was that they would fall into the hands of an unscrupulous being who could even remove all their freedom.
After all, the hell crown had the power to take over the mind of its user. Unless someone possessed exceptional mental strength or was freed by a superior, there was a high likelihood that the absorption would alter the mind of that person.
Mylecent moved on, feeling her existence shake inside her own body as her necromancer senses intensified. She managed to partially block the restrictive effects of the crown, but still felt part of her mind being taken over by a silent darkness, which merely made her feel reverence and obligation towards the blue-haired figure in front of her.
