Pitch black night and caves. Yet another modern maintained fork of the 'True Darkness' mod for Fabric! Available for 1.21+
This is a fork of True Darkness Refabricated, which is a fork of True Darkness by Grondag, maintained for Fabric 1.21+.
Grondag is the original author and all credit belongs to him.

Moody brightness not dark enough? Do you want nights and unlit caverns to be pitch black? This mod is for you!
In addition to maintaining the mod for newer versions, this fork also fixes compatibility issues with Distant Horizons and adds some server-side functionality, such as config syncing.
This fork completely removes Moon Phases, meaning the world is always pitch black at night.
