Last year, I drew this image of a sus Eclipsed Apprentice!Vozeo Among Us. In paint(dot)net. With a mouse.
I posted it on DeviantArt with a title that implied that I was posting an image that contained VERY heavy spoilers for Volume 1 of Arc 1 of The Fenrathae Saga. And I put a mature content filter on THIS image. In the description, I pointed out that I will never give away spoilers that heavy that freely.

If I ever post artwork relating to The Fenrathae Saga that contains spoilers in some way, I'll make the artwork in such a way that unless you know what to look for, you won't understand what's being spoiled! And if you ask me what's going on in the artwork, I'll just give you a very vague answer! If you ask me if such-and-such a thing is happening in the artwork, I'll just tell you that you're gonna have to find out yourself in the comic when it's posted!
