A NeoForge chaos mod firing random events at regular intervals — 81 happenings across 4 tiers, unlocked by exploring the Nether, the End, and the Deep Dark. No two sessions will ever feel the same. Actively in development.
🌀 What is Happenings?
Happenings fires random events — called happenings — at regular intervals, independently for each player. The further you explore the world, the stranger and more powerful the events that can befall you. From blizzards and blood moons to alien invasions and Herobrine sightings, chaos is always just around the corner.
The mod features a dual scheduler: normal happenings fire on a configurable per-player timer, while weather happenings trigger automatically at dawn and dusk with a configurable chance — keeping the world feeling alive at all times. Only one weather can be active at a time, and the last 3 weather events are remembered to prevent back-to-back repeats.
⚠ This mod is actively under development. New happenings, balance changes, and features are regularly added. Some happenings may be temporarily disabled or incomplete between versions.
🔓 Progression System
Happenings are gated by exploration. New tiers unlock as you venture further, ensuring early-game players aren't overwhelmed while veterans face increasingly unhinged chaos.

Each player's progression is tracked individually and persists across server restarts.
🌦 Weather Happenings
Weather happenings affect the entire server and trigger at dawn (day events) or dusk (night events). Only one weather can be active at a time per phase. The last 3 weathers are excluded from the random pool to prevent repeats. All weather events properly detect sleep and /time set commands to end early and cleanly release the weather slot.
