You get the ability to draw, but you realize that no matter what, you can only draw this creepy face that ends up appearing in your dreams.
It frightens you.
You decide that, after several months of seeing this dream, and being forced to draw this face on everything you can through an unusual form of magic after effect, you are mentally ill and go to see a doctor. The doctor, as it turns out, is a demon and tries to kill you. You end up having to fight your way out of a demonic hospital with only your wit and a very sharp pencil.
No seriously, the thing is freakin' sharp. Cheers to the manufacturer of that sharpener you used.
Anyway, you get outside and see that the whole world has been altered, and that creepy face has replaced the sun. The sky is now orange with black clouds, the grass is all dead, no animals are found anywhere in sight, and all the people have been turned into ravenous zombies craving flesh.
Only YOUR flesh.
To make things worse, your new-found OCD for drawing on stuff has kicked into overdrive and you can't fight the urge. You start to draw the creepy face on the dark pavement with your pencil and are eventually eaten by the zombie horde.... all the while drawing that evil face.
When you die, life returns to normal.
