🌌 SkyBlock Horizon (Server-Side Core)

A complete, premium, and feature-rich SkyBlock system designed specifically for NeoForge 1.21.1.

Unlike other mods, SkyBlock Horizon runs 100% on the server side. Players can connect to your server using a completely vanilla Minecraft client—no downloads or installs needed on their end!

✨ Key Features

🌌 Complete Void Generation (With Stronghold Support)

• Generates a completely empty void world (no land, no water, no grass, no ruined portals, no dungeons).
• Strongholds are preserved! Players can still find and use the End Portal to defeat the Ender Dragon and access the End.
• Includes a balanced Starter Chest containing only: 1x Oak Sapling, 1x Wheat Seeds, 5x Bread, 1x Water Bucket, and 1x Lava Bucket.

🏪 Double-Chest GUI Shop (/shop)

• A full, beautiful server-side Chest GUI. No ugly text links!
• Offers customized trade menus for buying and selling items in amounts of 1x, 64x, or Sell All.
• Features categories like Blocks, Farming, Ores, Food, Mob Drops, and Decorations.

🧬 Diverse Mob Spawner Tiers (T1–T3)

• Buy custom spawners for 18 different mobs divided into three tier categories: Common, Advanced, and Elite.
• Tier 1: Standard spawners with default spawn rates.
• Tier 2: Faster delay, increased spawn count.
• Tier 3: Ultra-fast delay, maximum spawn counts for ultimate grinding.
• Properties are safely injected server-side via custom NBT data.

🛒 Player-to-Player Market (/market)

📈 Balanced Base & Ore Upgrades (/skyblock upgrade)
