Inviting Formations are naturally spawning objects exclusive to Don't Starve Together, introduced in Return of Them. One of each type will spawn on the Lunar Island in the Lunar Mine biome.

They can be mined to obtain the different pieces of the Celestial Altar.

Their positions can be indicated by the Astral Detector.
