Queen's Domain Trident Keys: all five, the doors they open and the Petrified Garden order
Quick answer
There are five Trident Keys, one each in purple, blue, green, red and black. One comes from the Trident weapon at the start of Obmuer Temple, which breaks once it reaches weapon level 5. Players place two more in the temple; the Sapphire one is on screen in its dark flooded halls. The merchant sells one, shown on screen as the Amethyst for 15. The fifth, the black key, comes from the boss of the Petrified Garden. Players say the temple's main door needs only three, and the merchant's extra key makes that puzzle easier. You can take placed keys back out, and you need all five for the Petrified Garden statues and a hidden passage on the starting island.

Before you start
Kingy has played only the opening, not Obmuer Temple. The Sapphire and Amethyst keys and the key-choice popup are checked on screen in creator footage. The other sources and doors come from players' Steam reports, which don't always agree, as marked below.

Where the five keys come from
On screen, the key items list names four keys: Sapphire, Emerald, Ruby and Amethyst. At a trident door, a popup lets you choose which one to place. The fifth, black key comes much later. Players list the colours purple, blue, green, red and black at the Petrified Garden statues, which fits four gem keys plus the black one.

Obmuer Temple's main trident door takes three keys, and players stress that it is a puzzle you can solve with three. If you can't manage it, the merchant's key, which is on sale after the Tower of Knowledge boss, makes it easier. One player adds that further in, a door takes two keys and another after it takes two more. Destructoid's weapons list puts the Engraved Halberd behind the three-key gate.
One player insists there is also a door with four trident slots: they jumped out of a window early in the temple, where the first toxic fish creature leaps through, and followed the water around to it. Nobody else has confirmed it.

Place three keys in the main door and work the puzzle; you can pull keys back out to rearrange them.
Short of keys? Buy the merchant's after the Tower of Knowledge boss.
Save at a Crystal Monument after placing keys: one player warns that dying before a save can leave keys stuck in a door that your save doesn't know about.
One player says you reach the Petrified Garden by jumping out of the teleporter in the middle of a fast-travel trip. If it's your first visit, beat its boss for the fifth key. Then put one key in each of the five centre statues by colour: Beetle purple, Stag black, Slime blue, Bat green, Fishman red.
Two players agree on those pairings but list them in different orders (one goes Beetle, Stag, Slime, Bat, Fishman, the other Beetle, Slime, Bat, Stag, Fishman). Matching colour to statue seems to be what matters, but that isn't settled. Waking the garden brings some statues to life and they attack at once. Players add two more pieces, and how they connect isn't clear: one describes a crowned statue near the centre that shows up with all four lenses on the mask, and another says a duck statue from the garden, together with some Silver Etched Skulls, unlocks merchant charms that show collectibles through walls.
One player's way in: jump out of the teleporter mid-trip.
Beat the boss for the black key if you don't have five.
Beetle purple, Stag black, Slime blue, Bat green, Fishman red. Then be ready to fight.
One player found a secret door in the bushes on the starting island, to the left of the entrance to the shortcut behind the well, near the tree with three forest eyes. It takes three keys, and the room behind it takes two more. Another player says five keys open a path by the underground passage near the well, which fits the same two doors. One player believes this area wasn't in the demo.

Beat the whale/water level boss, but still only have 3 trident emblems?? Where's the 4th? ↗30 posts. Two players say a door needs three Trident Keys and that a fourth can be bought from the shop after the Tower of Knowledge boss. One player lists five: one from breaking the Trident, Sapphire and Emerald in the temple, Ruby from the shop and a fifth from a whale boss in the Petrified Garden. Others describe a secret area near the start with doors needing three and then two. Re-read November 7: one player gives four sources (the gate, the Trident breaking at weapon level 5, a wall near the second save crystal by the two-and-three-key gate, the shop after the next boss); another says Spirit oil breaks the Trident at once, and that placed keys can be taken back out.Reported ·
why no continuous save... ↗38 replies. Players explain saves happen only at crystals and that death reloads the last save. TheLobsterClause's crash put them back about 5 minutes, not an hour; Broso says the game keeps continuous saves for crash protection that the player cannot load, and links a Workshop quicksave mod; 3ink warns dying without a reset can soft-lock placed trident keys.Reported ·
