Eternal Protocol
by houlaiO0
With Eternal Protocol installed, a Forge world can enter a permanent night that the player must survive for 246 nights to win.
What it does
Eternal Protocol is a lightweight Forge minigame that leaves vanilla gameplay unchanged until the player chooses to start the challenge. The player crafts an Eternal Contract from an Amethyst Shard, a Redstone Torch and Paper, and using it begins a night that does not end. Time stays frozen at night, monsters spawn continuously and mobs become hostile and faster. The run is won by surviving 246 full nights, after which daylight returns.
The difficulty is locked to Hard, and Creative, Spectator and peaceful players are ignored by the mobs. On day 246 a choice event appears with clickable chat buttons and commands, so the player decides how the run ends. Spawn rates and other values can be configured. The server and every player need the mod installed. Files are published for Forge 1.20.1 only, with version 1.0.0 as the latest file, released under All rights reserved, which means the license does not allow open-source redistribution.

What the author says
Eternal Protocol is a lightweight Forge mod that doesn't alter vanilla gameplay, but adds a "final challenge" for players who want it. You start in a normal world, with daily broadcasts counting the days. When you reach day 246, the world offers you a choice: will you sign a pact and step into eternal darkness?
