Lies of P All Trinity Key & Sanctum Locations

Lies of P contains 5 Trinity Key and Sanctum Locations. Discovering all Trinity Sanctums unlocks the End of Riddles trophy & achievement.

Trinity Keys are obtained by answering the King of Riddles’ riddles at specific locations in the game. The way you answer the riddles has no implication on which story ending you’ll get. All riddles should be answered correctly in order to obtain the Trinity Key. You can still obtain the Trinity Key for some of them, even if if you pick the wrong choice, but for some of them, the King of Riddles will ask you for items you may not have, may have already used for other Side Quests, or will plague you with some temporary elemental damage. Once you’ve obtained a Trinity Key, you can use it to unlock a Trinity Sanctum at specific locations in the game. All Trinity Keys are needed to unlock the 5 Trinity Sanctums. Below is a list of all Trinity Keys and Sanctums in chronological order.

Krat City Hall Courtyard

Trinity Key: after opening the gate to the factory district, continue on until you reach a bridge with many bomb-throwing puppets. Before crossing the bridge, head right to find the first ringing telephone and riddle. Solution: Human.

Workshop Union Culvert

Trinity Sanctum: from the Stargazer, go through the tunnel with the rolling ball of fire to return to eventually find the Red Fox and Black Cat. Continue past them and head right when you come to the split with the big red pipe. You’ll eventually find a green door on your right you can unlock using the Trinity Key above.

St. Frangelico Cathedral Chapel

Trinity Sanctum: you’ll eventually reach a section with an electrified ball rolling down in your path. Go up the first slope, then immediately check your right for a ladder. Climb it up to reach the Sanctum. You can open it once you have obtained the Trinity Key at Malum District.

Malum District

Trinity Key: when you reach the square with the Decay throwing enemies on the upper section, continue down the main path and you’ll come across the ringing telephone. Solution: Candle.

Estella Opera House Entrance

Trinity Sanctum: you’ll eventually reach a room with a massive hole in the floor and a swinging chandelier. Drop down and turn around to find the Trinity Sanctum. You can open it once you have obtained the Trinity Key at Grand Exhibition Gallery.

Grand Exhibition Gallery

Trinity Key: shortly after meeting Belle and activating the bridge shortcut, you’ll find the ringing telephone in your path. Solution: Egg. After giving the correct answer, you’ll receive a clue stating “Before the fingertips of the cold woman in the Grand Exhibition”. Continue on and when you get downstairs, check your right for two statues. One of them can be moved. Move it so that it reflects the one you can’t move. A secret compartment will then open and you can collect the Trinity Key. You can now use this Trinity Key to open the Trinity Sanctum at Estella Opera House Entrance.

Krat Central Station Lobby

Trinity Sanctum: from the Stargazer, head down the stairs on your left to find the Sanctum. You can open it once you have obtained the Trinity Key at Krat Central Station Street.

Krat Central Station Street

Trinity Key: from the Stargazer, walk through the archway, go left, right, and left again to find a ringing telephone. Solution: Ergo. Once the Stargazers reactivate, you’ll then be able to open the Trinity Sanctum at Krat Central Station Lobby.

The Chosen One’s Trinity Key: once you’ve obtained all Trinity Keys and opened all Sanctums, return to this ringing telephone and answer the next question either way. As a reward for answering all riddles, you’ll also get King of Riddles’ Surprise Box which you can open in your Collectible menu and obtain this Key.

Arche Abbey Outer Wall

Trinity Sanctum: when you reach the room with the beams in the middle, continue to the bottom floor to find the last Trinity Sanctum.
