Sleepy Hollows
by satisfyu
Sleepy Hollows adds a haunted biome with fog, gravestones, ancient structures, its own plants and wood, and a horseman boss that players can meet after gathering gear.
What it does
The biome is themed around cemeteries, mansions and cursed plant life. Thick fog, eerie gravestones and ancient structures set its tone, and it brings new plants, trees, grass and stones alongside new enemies. Infected zombies, slightly stronger than regular zombies, are the main foes here, and a rider roams the trails as a boss fight for players with enough courage and the right equipment.
The mod also includes unique weapons and a new armor set that players can collect, along with darkness-themed boss gear. Dread and a loss-of-sanity theme shape the experience, so the biome rewards caution. Sleepy Hollows requires Architectury API, Biolith, Cloth Config API and TerraBlender, and it runs on the client and the server, so both sides need it. Files are published for Fabric, Forge, NeoForge and Quilt for 1.20.1 and 1.21.1, under a custom license that is not open source.

What the author says
In Sleepy Hollows, shadows grow, Where mysteries and whispers flow. The cemeteries, cold and still, Hold secrets buried 'neath the hill. A rider roams the haunted trails, With hollow eyes and armor pale. Infected plants, with twisted vines, Entangle dreams, distort the mind.
