Trinity Key & Sanctum Locations
Throughout your journey in Lies of P, you’ll encounter mysterious locked doors with a strange symbol, and you’ll answer phone calls from the “King of Riddles”. But how does it all connect?
This page acts as a comprehensive breakdown of how Trinity Keys work, where every Trinity Sanctum can be found, and the rewards within.
What Are Trinity Keys?
Trinity Keys are Key Items within the game, and are obtained by answering the King of Riddles correctly via the various telephone booths dotted throughout the city of Krat. They allow you to open the locked doors to the Trinity Sanctum rooms that you’ll likely have encountered as you explore.
What Are Trinity Sanctums?
Throughout Krat you’ll occasionally find a set of green locked doors, often illuminated with a single spotlight overhead. If you attempt to interact and open these doors, it’ll tell you that you need a Trinity Key. Each door also has a symbol painted on it, demarking it as Trinity Sanctum. Each Sanctum will contain at least one small readable piece of lore, and all with the exception of one contains a safe that will reward you with one of the following; a weapon, an outfit, upgrade materials.
Trinity Key Locations
Krat City Hall Courtyard
Once you have opened the gate heading towards the factory, you’ll eventually reach a bridge with multiple bomb-throwing enemies. If you walk straight past the bridge (instead of crossing it), you’ll see a ringing telephone illuminated in the distance. Speak with the King of Riddles on the phone and answer:
- Human
Malum District
After reaching the square with enemies that throw Decay on the rooftops, as you loop around and open the gate shortcut back into the square, you'll find a small room up the ladder by the shortcut where you’ll find the telephone. Answer the riddle with the following:
- Candle
Grand Exhibition Gallery
After activating the overhead bridge shortcut within the Grand Exhibition main hall (and speaking to Belle if you choose to), you’ll find the telephone in your path. Answer the riddle with the following:
- Egg
After the phone call ends, the King of Riddles will have given you another clue relating to the “fingertips of the cold woman in the Grand Exhibition”. Head down the nearby stairs and turn to your right to find two smaller statues with a larger one in the center. Turn the smaller statue to match the other one and a compartment in the large statue will open, rewarding you with the Trinity Key.
Krat Central Station Street
As you explore the now destroyed area surrounding Krat Station, take the side path that leads you to the cliff's edge. Turn left and you’ll find the telephone. Answer the riddle with the following:
- Ergo
Relic of Trismegistus
After collecting all previous Trinity Keys and using them to open the Sanctums, you'll find a phone overlooking the pit you need to drop into prior to the second Black Rabbit Brotherhood fight, and you'll speak with the King of Riddles. He'll ask you whether you are a killer or not.
Regardless of which answer you give, he’ll give you The Chosen One's Trinity Key or the King of Riddles’ Surprise Box. If you receive the box, open this within the Collectible tab of your menu and you’ll get this special key regardless.
Trinity Sanctum Locations
Workshop Union Culvert
From the stargazer head up to where you met the Red Fox and Black Cat (overlooking the Puppet of the Future pit), go through the passageway across from them and take a right instead of going through the large red pipe. There you’ll find the first Trinity Sanctum of the game. This can be unlocked with the key you acquire near Krat City Hall Courtyard.
St. Frangelico Cathedral Chapel
As you explore the depths of the chapel, you’ll find a section with continuous rolling balls that are electrified. Head up towards where the balls are coming from and then take the ladder on your right. There you will reach the Trinity Sanctum. You can return to this Sanctum after acquiring the Trinity Key from the Malum District area.
Estella Opera House Entrance
This one is easy to keep track of. From the stargazer head inside the Opera House and go straight ahead towards the flaming swinging chandelier (which you need to cross to face the King of Puppets). Drop down off either side into the dark below and you’ll find a Trinity Sanctum door waiting for you. You can return to this Sanctum after acquiring the Trinity Key from the Grand Exhibition Gallery area.
Krat Central Station Lobby
From this stargazer, all you need to do is go left down the stairs and you’ll immediately find the Sanctum. This Sanctum can be opened with the Trinity Key you acquire at Krat Central Station Street (post-earthquake)
Arche Abbey Outer Wall
When you reach the giant vertical room with wooden beams acting as bridges, head all the way to the bottom and you’ll find the final Trinity Sanctum. This is the Sanctum that can be opened with The Chosen One’s Trinity Key.
