Eclipse Expansion is a dark fantasy mod for Minecraft 1.21.1 (NeoForge) that adds a mysterious biome, eldritch entities, and a deep lore experience centered around a cosmic eclipse event.

Features:

Valle del Eclipse — A unique biome with custom trees, ore, and a constant ominous atmosphere
The Eclipse Event — A periodic solar eclipse that changes the world around you
Rednal — An invisible, immortal entity that follows a chosen player, whispers to them, and drains their life if it gets too close. It cannot be killed
The Eclipsed Wanderer — A humanoid creature that roams the Valle del Eclipse and drops Eclipse Essence upon death
Eclipse Armor — A full armor set crafted from Eclipse materials
Flower of Silence — A craftable item that repels Rednal for 3 Minecraft nights
Three lore books — Discover the history of the Valle del Eclipse through a deteriorated diary, an explorer's field guide, and a researcher's investigation notes, all written in a mix of Spanish and Latin
Custom sounds and particles

How does Rednal affect your experience?
Rednal spawns randomly and targets a player. It follows them invisibly, teleports behind them when looked at, whispers cryptic messages in chat, and slowly drains health if it stays close. The only way to stop it temporarily is the Flower of Silence or the Eclipse Candle.
