Game of Thrones: Conquerer

Nocturn's scales are a deep, midnight blue that appears almost black in most light. When moonlight touches its scales, they shimmer with a subtle, starry iridescence. Its eyes are a piercing silver, glowing in the dark. Nocturn's wings have a unique, tattered appearance, resembling a starry night sky when spread. It's slightly smaller than average dragons but more agile.

Incapable of human speech like all dragons, a mythical beast, even still Nocturn is highly intelligent and cautious, preferring to observe before acting. It's fiercely loyal to its rider but wary of others. Unlike most dragons, Nocturn is nearly silent in flight and can exhale a cold, shadow-like flame that temporarily blinds enemies. It's most active and powerful at night, drawing strength from darkness.

Born from an egg thought to be petrified, Nocturn emerged during a rare celestial event. Raised in secret by a rogue Targaryen descendant in the Shadow Lands beyond Asshai, Nocturn developed unique abilities tied to darkness and stealth.
