Mortal Shell 2: Abbey Entrance Beacon Location and How to Cleanse It

Abbey Entrance is one of 49 beacons in Mortal Shell 2, tucked into the Ruins of Mammon near the traversal gate south of the Abbey. Rest at it and you top up Health and Resolve. Cleanse it and you drop into the Kingdom of Fools, a short dungeon that ends with a boss and an Ovum.

Quick answer: Fast travel to the Outskirts of Mammon beacon, cross the Bone Gate and follow the ruins southeast to reach Abbey Entrance, then choose Cleanse Beacon, grab the Strange Village Key in the Kingdom of Fools, unlock the wooden gate, kill Bor, the Deluded Monarch, and cleanse the Ovum at the edge of his arena.

Route to the Abbey Entrance beacon from Outskirts of Mammon

Outskirts of Mammon is already cleansed when you find it, so it is the default drop point for the whole region. Use it as your starting line.

Travel to the Outskirts of Mammon beacon and head out through the canyon, passing the catapult. Follow the path until you reach the white rift portal and step through it.

On the far side you land in a ruined stretch of Mammon. Before pushing on, check behind the large tree root near the exit for a Bloodseed.

Kill the enemy guarding the entrance and move into the dark stone temple. The first room holds three enemies and a set of sarcophagi you can loot for Coins and Extracted Ignisium.

Climb the stairs at the back of the room and attack the wall at the top. It breaks open to reveal another sarcophagus holding the Tyrant’s Stone, a Tarstone that is easy to walk straight past.

Carry on through the temple, clear the enemies gathered near the statue, then leave by the far side. Cross the bridge and follow the narrow cliffside ledge until the beacon appears in front of you.

Touch it to log the BEACON FOUND prompt. That registers Abbey Entrance as a respawn point even before you cleanse it, which is worth doing before you commit to the dungeon.

What cleansing Abbey Entrance gives you

Every beacon you cleanse counts toward the So Fresh, So Clean achievement, and all Ova in the game come from cleansed beacons, which feeds the Bring My Ova Back to Me achievement as well. Clearing the Kingdom of Fools pays out the following.

Reward	Where it comes from
1,000 Coins	Chest in the first room, before the lift
Ventrium x2	Skeleton and containers in the village
Glimpse x1	Dungeon clear
Gloom	Bor, the Deluded Monarch
Monarch’s Vestige (Tarstone)	Bor, the Deluded Monarch
Ova x1	Corrupt core at the edge of the boss arena

Note: cleansing also strips the corrupted growth off the beacon itself, which clears obstructions that block nearby loot and unlocks the full beacon menu.

Kingdom of Fools: Finding the Strange Village Key

Interact with the beacon and pick Cleanse Beacon to enter. The dungeon is compact, but the exit is locked behind a key that hangs in the far corner of the village.

Run down the opening corridor and open the chest in the first room for 1,000 Coins. Then take the wooden lift at the end of the hall.

At the bottom, walk forward and hit the door blocking the way. It breaks apart and opens onto the burning village.

The first villagers here are passive and can be ignored or killed for materials. Head past the well in the middle of the village toward the gap at the back, where the enemies turn aggressive.

Open the chest against the wall beside the gap for more Coins, then turn left and search the skeleton nearby for a Ventrium.

Follow the path to its end. The Strange Village Key hangs from a chain inside a fleshy pod at the back. Destroy the pod to drop the key, and watch for the coffin monster waiting underneath it before you pick it up.

Return to the well and turn left to find the large wooden gate. Use the key on it, then drop down the hole just inside the entrance.

Beating Bor, the Deluded Monarch

The drop lands you straight in the boss arena, a cave with no run-up and no second beacon, so heal before you jump. Bor is a large, slow-swinging opponent, and the fight is a straight duel rather than a mob encounter.

Killing him hands over the Monarch’s Vestige Tarstone along with a Glimpse and some Gloom. A few stragglers may still be roaming the cave afterward, so sweep the arena before you go looking for the core.

Cleansing the core and confirming it worked

The corrupt core sits at the edge of the boss arena once Bor is down. Interact with it to cleanse it and collect the Ovum. You will see the BEACON CLEANSED message, which is the only confirmation you need.

Back in the overworld, the beacon loses its dark overgrowth and the menu expands. Alongside resting, you get Level Up, Change Shell and Sub-Items, Change Shades, Change Masks, Change Mortal Clothing, Mether’s Pulse, Mether’s Breath for fast travel, and Return to Marrow Keep. Abbey Entrance also now shows up as a fast travel destination from any other beacon.

Why the cleanse might not complete

The wooden gate stays shut without the Strange Village Key. It only drops after you destroy the hanging pod at the end of the path behind the village.
The corrupt core cannot be interacted with until Bor is dead. Leaving the dungeon early resets your progress through it.
Resting at the beacon respawns every regular enemy in the area, including the village mobs, so re-entering means clearing the route again.

None of this is missable. If you push past Mammon without touching Abbey Entrance, you can come back for it in free roam after the final boss, before you decide to start New Game+.
