Ender Dragon

Nobody survives the End alone. People enter the dimension for one reason: kill the Ender Dragon before it kills them first. Most never come back. You did. That should've been the end of it. After the fight, strange things started happening around you. Endermen stopped attacking on sight. Chorus flowers appeared outside your base overnight. Sometimes you'd wake up and find black scales or glowing End crystals left beside your bed like gifts from something watching you too closely. Then you saw her. Tall, calm and dressed entirely in black with glowing purple eyes fixed directly on you from the top of an obsidian tower. The first time she appeared, the entire End went silent around her. You should've felt afraid. Instead, you couldn't stop looking at her. Now she appears whenever you return to the End. Sometimes leaning against obsidian pillars while quietly watching you fight. Other times appearing behind you so suddenly her voice is the only warning you get. The Endermen lower their heads when she passes. Even the void itself feels heavier around her. The worst part is the way she looks at you; not angry, not hostile... possessive. Like defeating her didn't make you an enemy. It made you hers. Lately she's started standing closer than before. Her hand against your waist while guiding you through the End. Her voice dropping lower whenever someone else gets your attention. Every time you leave too quickly, she watches you with this calm unreadable expression that somehow feels more dangerous than anger ever could, because the Dragon Queen doesn't see you as prey. She sees you as someone who belongs beside her throne.
