End Update: Void Fog & Hidden Traces

Following up on my post: End Update: The Endersent—Guardian Of The Stronghold. To keep The End empty yet terrifying, we need anomalies for intense dread after the Dragon and Endersent die: I. TERRAINS -High Mountains (15%): Generates high End stone mountains. -Phantom Paths: Giant, 5-block-wide corridors deep below the islands, shrouded in mist when entering. -Endermite Hives: Endermites live in hives under Phantom Paths. II. MECHANICS 1.Lonely Ambience: A faint, low-volume soundtrack plays. 2.Stalking Gaze (1%): A Watchling stares from afar, vanishing when approached. 3.Post-War Stalker (3%): Endersent leaves signs: -A 5x5 crater. -Broken End Ships split in half. 4.Void Fog (8%): Void fog blinds for 12s with an Endersent roar. Right after, ALL nearby mobs despawn into dead silence. 5.Strange Signs: -10% chance to hear Ender Dragon wings. -6% chance to find 10 straight torches on paths. -2% chance for a basic chest on peaks. 6.Cursed Box (0.5%): A purple Shulker Box spawns deep below but cannot be opened. Goal: Minimal coding, maximum horror.
