A moody PaperMC plugin that turns underground mining into a quiet, introspective, and slightly unsettling journey. It completely strips away flashy particles to focus on isolation, soundscapes, and raw psychological depth.

The Concept

As players descend deeper into the earth, the world slowly changes. FOG tracks player depth in real-time and triggers subtle atmospheric changes depending on their current zone:

• Shallow (Y: 59 to 30): Warm nostalgic thoughts, gentle cave echoes, and the quiet comfort of a furnace.
• Deep (Y: 29 to 0): Heavy silence, deep reflections on why we keep digging, and distant machinery.
• Abyss (Y: -1 and below): Existential dread, raw cavern echoes, and sudden 10-second warden blindness.

Features

1. No Particles

There are no floating bubbles, colorful dusts, or flashy indicators. The atmosphere is built purely on ambient sound cues, raw text, and sensory deprivation.

2. Warden Darkness

When an atmospheric trigger occurs in the Abyss, the player is struck with a pure, black Darkness effect for 10 seconds (200 ticks), simulating a warden passing by in the dark.

3. No-Repeat Message Pools

To prevent spam, the plugin tracks which thoughts a player has already experienced during their current zone visit. It will never show the same text twice until they leave the zone (which resets their history). If a player has seen everything in a zone, the whispers fade to absolute silence.

4. UI

The help and status interfaces are designed with a retro psychological horror aesthetic:

• Spaced lowercase styling.
• A custom Adventure color gradient for the f o g title (shifting from indigo #311D3F through blood crimson #881A30 to pale red #E23E57).
• Unified silent prefixes (f o g ») for all status and error messages.
