They at least landed somewhere? Gav blinks the afterimage away to see where they landed.

They seem to be inside a... jail cell? A jail cell in a dungeon? It's dark and cold and damp, the wall and floor are bare stone with moss growing from the cracks, there is a bedroll next to a wall with a skeleton lying on it, and the door to their cell is a heavy metal gate embedded into the stone.

Also, they're naked.

Naked in a jail cell? That brings back some pleasant memories, but the skeleton is creepy.

Unarmed in a jail cell in a dungeon. Could this have been the goal? Imprison them somewhere unknown? Actually, Herod opens his magic sense to see if anything in the room is magical.

Nothing in the room, no, nor in the hallway beyond.

Any chance that the door is actually unlocked? Alternatively, can they force it open? Gav casts improve strength on himself first.

The door doesn't have a lock, per se; it's a portcullis, and the only way to open it is by pulling it up and into the wall. Which Gav can pretty handily do.

Well, if someone brought them here on purpose, they would have done a better job at security. Probably. They might still be shot by someone, if they go gallivanting naked about the unfamiliar place, but beats keeping the skeleton company.

Herod crosses the portcullis, hurdling his wings closer to his body.

Gav waves the skeleton goodbye and follows suit.

The hallway has more cells, not all of whose doors are closed, not all of which contain skeletons. The meagre light that's the only thing letting them see comes from a single wall torch at the other end of said hallway, and from there and to the left there is a ramp gently sloping up.

They give the other cells a cursory glance, mostly to make sure there isn't anyone else in need. Is the torch removable from the wall?

With some super strength it can be yanked free.

A meager source of light: acquired.

They then proceed to the ramp to the left.

Their footsteps don't echo because they're barefoot but it feels like they should be. The place feels the kind of cold that deep underground places often do, a humid breezeless cold that seeps into your bones and leaves your teeth chittering. The lit torches are sufficiently far from each other that there are occasionally stretches of actual darkness. It's unclear why anyone would go through the trouble of only lighting some of these torches, if they already went as deep as this holding area seems to be.

After some walking they reach a pair of stone doors. One of them is cracked but still standing, while the other has crumbled to pieces and allows them to squeeze through. On the other side they can see a large circular chamber with three more doors similar to that one on the "ground floor", all of them mostly-intact. The center of the room is dominated by a thick cyllindrical pillar around which a set of spiral stairs leads up to a metal grate door on the ceiling, and from that direction they can hear voices, faint enough their sources are probably pretty far away.

For once, even Gav thinks this is a bad time to be naked. Is there enough room to fly?

They can take the stairs otherwise. Herod whispers to Gav about the distant voices. "Let's try approaching silently, first. Just in case they are our captors."

The ceiling isn't high enough to permit flight, no. Getting to the door doesn't really let them discern what the people are saying very well, but it does let them pick out two different voices. They seem to be walking away from wherever Gav and Herod are, though.

Are they capable of discerning anything that is being said? At least emotional tone?

No and yes: it seems like those two are just having a calm conversation, perhaps a bit dry with short sentences but not otherwise remarkable.

Not a lot to go on.

Okay, what if he and Gav worked together to slowly open the metal gate without making too much noise?

It... still makes a fair amount of noise. They can certainly reduce it from what it would have otherwise been, but it's still a probably-centuries-old grate sliding into stone, there's not much they can do, there.

That said, it does not seem like it grabs the attention of those two people; their voices continue to fade away into the distance.

Cool, Gav is a big guy (in more ways than one), but he tries to be careful. Maybe they can close in the distance enough to hear whatever the two voices are saying?

The room they step into is another circular room of the same diameter as the one they just left, but much less empty, with old rotten furniture and books strewn about here and there. There is a single, large opening on the wall leading into another hallway, and that's where the voices are coming from. If they follow the voices they'll find themselves going through a maze of corridors in what is increasingly obviously ancient buried ruins of some kind.

Eventually they do get close enough to be able to make out words.

"...on the floor over there," says one of the voices. "My guess is... fire? I think it's fire."

    "I'll defer to your judgment," says the other voice. "'Tis not my area of expertise."

"Nor mine but I suppose it's probably more mine than yours."

Herod briefly considers looking around the rotten furniture for a source of modesty, but decides against it.
