An gouache landscape painting with heavy canvas texture of a panicked medieval castle kingdom. In the background is a tall narrow erupting volcano, with an ancient massive, armored subterranean wurm coiled around it. The creature has a dark grey segmented underbelly, black spiky segmented plates along its back, and an huge roaring beak-like gaping mouth with a dark hollow interior. Burning forests surround the volcano, encroaching towards the kingdom. Bleak red sky filled with smoke and ash. Dynamic camera angle with foreshortening. Dark fantasy, haunting, atmospheric horror art style.
