Obelisk

The Obelisk is an Interactible found in the Hidden Realm: A Moment, Fractured, which can only be reached via the Celestial Portal, which spawns every three levels after the first loop next to the Teleporter.

The Obelisk takes the shape of two gigantic, slab-shaped monoliths which extend upwards for around 30 metres where a circular cavity is present. When activated, this cavity is filled by a ball of brilliant blue light.

The player can interact with the Obelisk, being prompted if they want to obliterate themselves from existence, then being asked again if they are sure. Doing so the second time will end the run for all players, while also giving each 5 Lunar Coins.

Obliterating for the first time complete the "True Respite" challenge, which unlocks the character Mercenary, while obliterating with any Survivor on Monsoon (except Engineer) completes their Mastery challenge, which unlocks that Survivor's skin.

If the player wants to continue the run, a portal will open up near the Obelisk (after interacting once) to the right side of the hill.

Obliterating yourself with the Dio's Best Friend won't allow you to continue your run.

As of the Hidden Realms Update, obliterating with a Beads of Fealty in your inventory will not end your run; instead every player will be teleported to the Hidden Realm; A Moment, Whole.
