I thought maybe I should make some kind of announcement about the spells I can do that are useful in this situation.
I can heal any type of wound. The more injured a person is, the harder it is to heal. I can also bring people back from the dead. I can only resurrect people three times a week. I think.
I have a spell I have never used before that would create a hallowed space. Within that space, everyone would be protected from the ghosts and anybody who has been possessed will be freed of their possession. I do not have enough incense with me to cast this spell, but if any magic user here has some high quality incense, I can work on this. Since I've never cast this spell before, I'm not sure how effective it will be.
I can also cast an aura around myself, which can extend to other people near me, that will protect you from harm from the ghosts. I tested it out with some of the ghosts and it is fairly effective.
I am able to banish ghosts, but they only stay gone for a minute, which I guess isn't really helpful in this kind of situation.
