Horizon of Darkness

I guess I haven't come up with any illusions yet.

I just came up with something like invisibility, in case a chameleon or liquid isn't suitable for the job. Or, simply, instead of the liquid, people would see some more familiar creature, although contact with it would still be impossible. I also added some magic just in case.
Initially, I wanted to create some kind of mind magic and combat magic (but not elemental).
