(Inspired by the Free TF-Raygun and one of the best stories on this site. I just wanted to make something with less restrictions, like being restricted to anthros.)
Somewhere, on the deep web, one would have for a short time been able to buy a magical device with the following description:
"Introducing, the TF-Pad!
This new, revolutionary device, created by Godcorp is capable of changing the world to your desires . Well, that is if those desires include transforming people into all kinds of things.
If so, we got what you oh so desperately need!
Just put the TF-Pad around your forearm, like a watch, point at the person you want to transform and then look at your Tf-Pad. (Max range of 20 meters. Don't point at someone on life-tv and expect them to transform. That is not how it works. )
Displayed there will be various stats on the person like age, gender, mental stuff and species. You can also turn awareness of the transformation on and off.
Just adjust those things by typing on your TF-Pad!
You will be able to watch the transformation on your TF-Pad even when your view of the person is obstructed by something.
REMEMBER, all PHYSICAL transformation are PERMANENT! MENTAL ones may be changed by you.
Anyway, thanks to cloaking magic the TF-Pad shouldn't be visible to anyone unless you allow them to see it. This is known to be somewhat bugged though. So be careful!
Another absolutely amazing thing about the TF-Pad is it's capability to alter reality. Sadly you can't control that function directly as that would violate several dimensional laws and we already had a fight with the Dimensional-Court. Several attorneys died.
What you can do is affect the past and present of a specific person. (You may turn them into a old friend of yours or stuff like that but you can't change the past and present of a thing or concept like a town directly.)
You can't cheat yourself into being the God-emperor of your reality instantly. If that so happens then it will be after you have transformed millions of people. Otherwise that would not be fun if you could just completely control your reality instantly.
So, be prepared for the world to change as you transform people. It will become a mess, but it will be YOUR mess.
Note here that the TF-Pad only allows you to turn the people you want to transform into Tier-1 to Tier-3 divine and magical beings. Anything above that would get you, us and the transformed person into trouble.
(You will only be able to create one such entity for every 100 normal transformed people to a maximum of five. You will need our expressed permission if you want more. You can contact our costumer department over your TF-Pad if you want that)
And the best thing is, all those transformed people will see you as their master and be loyal to you and you only!
But, if you abuse them your control over them will slip and we may deploy... additional measures to disrupt such behavior.
While we facilitate transforming people into your servants, we don't tolerate the abuse of said servants!
Even we at Godcorp have morals...not a lot, but still, we have them.
You may receive updates to your device as the TF-Pad is still being developed and getting new functionalities.
Also, don't worry about other people in your dimension possibly receiving TF-Pads. That shouldn't happen."
