SCP-001, The Scarlet King
by Zcoper
SCP-001, The Scarlet King is a Forge mob mod that adds the Scarlet King entity from the SCP universe, along with the cultists and rituals that come with his manifestation.
What it does
Once the manifestation is activated, cultists begin spawning in surface groups, chanting and performing rituals that raise the manifestation. As it climbs, the sky takes on a red haze, hostile mobs become tougher, blood rain starts, lightning strikes, and the world grows steadily corrupted until the Scarlet King appears in the overworld. The goal is to kill him, weaken the manifestation, and seal him with ritual chains before he manifests fully.
The mod can be played through several endings, depending on how high the manifestation was sealed, and one of them is complete world destruction. A new item called the Manifestation Clock shows the current manifestation level. Game rules control the state: scarletKingManifestation reports it, enableScarletKingMusic turns the music off, and scarletKingSafemode prevents the bad ending. Commands reset the manifestation or the bad ending.
Installation needs Geckolib, which must be present on the same Forge setup. Installation covers the server and each player's game. It is published for Forge only, for 1.19.2 – 1.20.1, with 1.0.0 for 1.20.1 as the latest file, and it is not open source.

SCP: Lockdown uses the GNU General Public License v3.0 only, targets Forge for 1.12.2 – 1.20.1, and also runs on client and server, so it covers more game versions than this mod.
