SCP-427, Lovecraftian Locket
by Zcoper
With SCP-427, Lovecraftian Locket adds a small silver locket that heals its holder while it stays open, then gradually reshapes them into something unrecognizable.
What it does
SCP-427 is an item from the SCP universe, where the locket is known as the Lovecraftian Locket. A small ornate silver locket lies on the ground and can appear anywhere in the overworld, in the manner of an ordinary hostile creature, yet only a single copy is present in each world. A player picks it up by right-clicking it, and places it back on the ground by sneaking while right-clicking.
While the locket is carried open in the inventory, the holder gains regeneration that cures harmful effects over time, and night vision and saturation strength. Starting with regeneration after 30 seconds removes poison and wither. Several minutes pass before the holder gets a mutation alert; soon afterward the host dies and the locket's contents emerge as SCP-427-1, a grotesque being formed from the corpse. The mod makes SCP-427 a double-edged tool: great power in the short term, and a deadly outcome when overused.
The mod requires Geckolib, and it runs on client and server, so the server and every player need it. Files are published for Forge only, for 1.19.2 – 1.20.1 across three release versions, under All rights reserved and not open source. The latest file is 1.0.0 for 1.20.1, published on 2026-06-10.
Key features
Healing and status effects
Carrying the locket open grants regeneration, night vision and saturation, and removes poison and wither after a short time.
Escalating transformation
Each minute the locket remains open raises the instability of the change, which ends when the holder is transformed into SCP-427-1.
Mutation warning
After several minutes the player is warned of a coming mutation, shortly before SCP-427 kills the host.
Pick up and drop
The locket can be picked up by right-clicking and set back on the ground by sneaking while right-clicking.
Single spawn
In the overworld, SCP-427 can show up like any standard monster, with just one copy existing per world.
