Chrystabel visited Sebastian to make sure he was safe. "Don't worry, once you are okay and it is safe, you are free to go." Chrystabel said. "School starts next week too."<br/><br/>Then Chrystabel brought Lilith to the demonology class. This was a class to introduce various demons and demon types by identifying their kinks and how they operate and kill. Most demons are brutes, and they enjoy killing and massacring humans. Few of them are smarter and target witches and can manipulate people.<br/><br/>The class was held in the basement in a new room, heavily warded with spells and a senior witch went through the lesson summoning a lesser demon and trying out fire on the demon burning it and the demon did not feel a thing. The immunities of the demon was shared and many of these demons are bounded to the caster to do a task and freed after. Demons when destroyed return to hell and usually bear a grudge against the caster, but unlikely they will get the same demon again.<br/><br/>The new room was soundproof and the senior witch summoned another demon, this one, a hellspawn. It looked like a human with dark skin and the witch used a gun and shot the demon but the bullets did not penetrate the skin. It was stronger and faster than humans and was considered very dangerous but it was vulnerable to holy and magical weapons, and a stab to the heart will send it back to hell.<br/><br/>The witch dismissed it and she looked considerable weak and Chrystabel saw the summon page of the hellspawn and it needed 1 liter of the caster's blood. The demon class was interesting as the witches get to meet and touch the demons which looked bored as they could not escape and was not allow to kill humans.
