The Gullet is a location in Torment: Tides of Numenera.
Background
The Gullet is one of the deepest parts of the Maw, where... Well, where anything is possible.
Points of interest
Welcome to the gullet. Talk to Vonetion to get a sample of the horrors awaiting you, then move on. The Gullet is three chambers arranged around a central pool of foul liquid. To enter the Nethermost Cavity and eventually the heart, you need to climb down the drain after stopping the flow of liquid.
The first tube can be sealed using the Sealant Spray or Sealant Bomb you can recover from a downed armored suit on the ground, in the far room of the Gullet.
The third requires you to use the Sealant Bomb or the white Synth Egg pilfered off the murden to plug up the tube.
Climb down the pool to get into the cavity below.
If you have the Magmatic Annulet, you can take control of the cluster of tongues with Intellect and send the combatants away (clearing the way for you), sense what's outside the chamber, or reopen the portal to the shrine of Great Chila (which is impossible, but worth a try).
The Predatory Echoes bar way to loot, which includes the Disruption Blade.
Further ahead stands a feral murden. With Concentration you can try to push through the psychic noise to get closer to it and kill it. Alternatively, you can use the Magmatic Annulet to knock it out. Both ways give you the Synth Egg and Candy Dispenser.
Standing over the whirpool is Siowan. Talk to him to learn of his desires.
Artaglio is in the Northeast if you previously let him to be devoured by the maw. He will confront you but you can help him by absorbing him in to your mind. He will appear in the Calm as a reflection.
You can rest in the folds near the suit. With the Annulet, you can commune with the Bloom tongues and force an ancient maw to reveal itself. To open it, interact with it to learn what it wants, then use Intellect (Persuasion) on Siowan to make him open it. It leads to the Chamber of Bones.
In the lower-left chamber you find Herja, if you fed her to the maw. You can use Intellect (Persuasion or Deception) to stop her from attacking you and make her disappear. If you approach the echoes, they will attack. Loot the corpse to find the Obedient Rope.
Speed (Quick Fingers) or use the Obedient Rope to do the same (the rope does cause the Predatory Echoes to go berserk).
Intellect and send the combatants away (clearing the way for you), sense what's outside the chamber, or reopen the portal to the shrine of Great Chila (which is impossible, but worth a try).
