Planescape is rad and I desperately wish to run a plane hopping game one day. My one attempt at it by mixing the Planescape adventures with the Rods of Seven Parts was...too ambitious (shocker). We really didn't get a chance to really appreciate the Planescape part of it so maybe one day I'll return to it with a simpler more focused adventure.
However, I did commission a bunch of art for each of the Planes. Maybe some people will find this useful. All of this is the work of the very talented Victor Sickman (here is their artist info). Are these accurate representations of the Planes? Absolutely. Probably? Enjoy the art and may it help you in your games and/or bring you some inspiration!
