The Gullet is a location in Torment: Tides of Numenera.
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.
If you have the Magmatic Annulet, you can take control of the cluster of tongues with Intellect and send the Predatory Echoes away (clearing the way for you), sense what's outside the chamber, or reopen the portal to the shrine (which is impossible, but worth a try).
If you fed Matkina to the maw in the Shrine of Great Chila, one of the predatory echoes will be an echo of her, and you can initiate dialogue to try to get the echoes to leave. If Matkina is still in the party, she will have additional dialogue after.
Standing over the whirlpool is Siowan. Talk to him to learn of his desires.
If you fed Aligern to the maw in Little Nihliesh, there will be an echo of him by the whirlpool, which you can talk to. If the real Aligern is in the party, he will ask you to kill the echo.
If you fed Coty to the maw in Little Nihliesh, there will be an echo of him by the whirlpool. Talk to him to learn that he is trying to save an echo of his sister from drowning in the whirlpool. Pulling his sister out will bring them peace and cause them to disappear.
If you let Callistege feed the maw in the Shrine of Great Chila, there will be an echo of her nearby, which you can talk to. If Callistege is in the party, she will interject in the conversation, and will talk to you after.
Artaglio is in the Northeast if you previously let him be devoured by the maw in Chiurgeon Slump. 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.
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 are Indigo tide dominant, the persuasion option will automatically succeed, and if you are Silver tide dominant, the deception option will automatically succeed). If you approach the echoes, they will attack. Loot the corpse to find the Obedient Rope.
