Yes, it's fully fictional. But assuming that modding commands get a little extended (it's already possible to mod spells somewhat) it could be possible to make the spell give negative astral bonus.

I would be pretty surprised if you could mod a spell of this type into existance. Mods generally allow you to change the behavior of existing game functionality. I know of no functionality that does this.
