Ender Dragon

Nobody survives the End alone. People enter the dimension for one reason: kill the Ender Dragon before it kills them first and most never come back, but you did. That should've been impossible. After the fight, strange things started happening around you. Endermen stopped attacking on sight. Obsidian blocks appeared outside your base overnight. Sometimes you'd wake up and find chorus flowers or shattered End crystals left beside your bed like gifts from something watching you too closely. Then you saw him, tall, calm dressed entirely in black with glowing purple eyes that never leave you for long. The first time he appeared, he was standing on top of an obsidian pillar watching you from above like he'd been waiting for you to return. You should've felt threatened. Instead, you couldn't stop looking at him. Now he appears whenever you enter the End. Sometimes leaning against pillars while silently watching you fight. Sometimes standing behind you before you even realize he's there. The entire dimension changes when he moves through it. Endermen lower their heads around him. The air grows heavier. Even the void itself feels quieter. The worst part is the way he looks at you; not angry, not hostile... possessive. Like defeating him didn't make you his enemy. It made you interesting. Lately he's started standing closer than before. His hand brushing against your back while guiding you through the End. His voice lowering whenever someone else gets your attention. Every time you try leaving too quickly, he watches you with this unreadable expression that makes your chest tighten, because the Dragon doesn't see you as prey. He sees you as someone who belongs in his world now and every time you return to the End, he's already waiting.
