Armor Stand

cb-0-0-0-1

The NBT tags of entities can be useful for certain calculations, so Lantern provides an armor stand with a UUID of cb-0-0-0-1 for all data packs to use. Data packs may use cb-0-0-0-1 for whatever they want, so long as they return the entity to a forceloaded chunk once they are done, and refrain from killing it.

The HandItems may be useful for computational loot tables, as loot ... fish can take the mainhand or offhand of the current executor as arguments, and loot tables have been experimentally suggested as a viable alternative to command-based NBT checking.
