Prompt

A vast, cracked plain glows gold in the alien sunset. A lone, emerald hill rises from the center, dotted with glowing runes etched on moss-covered boulders. A gnarled blackthorn clutches at its base. Above, a monstrous black tower, polished obsidian reflecting the vibrant sky, pierces the cloud cover. Strange fungi cast an eerie light on its surface. Blood-red windows pierce the darkness, while tendrils of electricity crackle around the cloud-shrouded peak.
