A massive fortress made of shimmering black obsidian rises dramatically against a stormy sky, its jagged towers piercing the clouds. Thick vines of glowing emerald wrap around the obsidian walls, while flickering torches cast eerie shadows. A dark river flows ominously at its base, reflecting the fortress's sharp angles. In the foreground, armored figures stand vigil, their eyes glinting with determination, ready to defend their realm against unseen foes.
