A colossal airship made from the skeletal remains of an ancient leviathan soars high above the clouds during a dramatic solar eclipse. Its hull, formed from fused bone and dark metal plating, pulses with eerie green light, while glowing runes carved into its spine-like structure hint at necromantic origins. Towering, membranous sails of stretched, translucent skin ripple as ghostly energy crackles along their edges. Below, the storm-torn sky churns with swirling clouds of deep cosmic hues, lit by flashes of spectral lightning. Despite the chaotic winds, the undead vessel glides effortlessly, an omen of doom against the backdrop of the eclipsed sun.
