Unless you have some drawing skills and a lot of time, it is likely you don't have a proper avatar for all of your characters. So you find yourself wandering around the web, hoarding unlicensed or generic pictures for safekeeping: perhaps one day, you'll use it to illustrate a PC or a NPC of yours.

Do not fret, noble roleplayer: you can now create cool-looking portraits using ArtBreeder, a platform that allows the creation of visuals based on machine-learning. The results are actually quite baffling and are more than suitable for any character (with some exceptions, like masked characters or faces with very specific details).
