I don't care for this on top of what others have said the name just feels goofy to me. Also considering how many zombies get made in a day id think there would be some casters hanging around the place, actually now that i think about it more employes period it looks like only 4 intelligent creatures are operating this entire building.
I don't like it that your race is so important a half orc can be taken out of action with just a couple hits but an elf has tremendous resistance.
I think this would have worked better if it just gave a penalty on people who failed a save and caused them to look like the next age category up. Rather then worrying about and keeping track of exact year counts
I like this one. I'm not certain why people keep mentioning weapon use, its human shaped so it can uses a weapon its default weapon is no better then claws so it doesn't increase the monsters threat. But it makes sense to have the dagger if it wants to defend itself and still maintain its illusion of humanity.
As far as I can see it never specifies that all members are female so I would not assume that is the case. A man can seduce people to.
