A GM screen I did for a small independent tabletop role-playing game (TTRPG) developer Mythos Forge Games, they are crafting a gothic adventure/horror game set amidst the landscapes of 14th-century Europe, entitled "Grimoires of the Unseen."

It was literally the longest illustration I have done. But I had a blast meticulously detailing every inch, you can see the process below and it looks so good on video.
