Deathbringer is an adult male NightWing and the main protagonist of Assassin. As an apprentice under his mother, Quickstrike, he formerly served as an assassin for the NightWings. He has since relocated to the Rainforest Kingdom. Deathbringer has black scales, eyes, and wings with a glittering spray of scattered, sparkling, silver scales underneath that catch the morning light like trapped stars. He is a lot younger and smaller than Morrowseer, and only a bit larger than Starflight. He is strong and astonishingly fast. He has a rakish, cheeky grin, and is wiry and graceful in his movements, even when he is startled. He is heavier than Winter and has clearly been trained to fight based on the way he stands and assesses others.
