Really depends on the party make-up classes, personalities, and alignments.
The hallway seems to go on forever in both directions, but only ten doors open to the glass key you recovered.
Door 1: A large red clay city stretches out from the door. A wooden sign with a painted eye hangs over a nearby shop. Warriors wearing chainmail veils walk past in the street. In a nearby alley two cloaked figures are passing something from hand to hand.
Is the painted eye a known symbol? How about the chainmail veils are they a known section of your world?
Doesn't really grab me though.
Door 2: The battlements before you seemed to be made of millions of shimmering diamonds. Below the wall, drifts of snow almost obscure an ice covered road. Could this be the Fortress of Frozen Tears. A domain of deepest winter in the Feywild. If it is, where is the silver path?
mmm interesting, am I prepared for Winter adventuring?
Has possiblities, I assume we have time to watch for a bit to judge it better.
Door 3: Grass huts and strange broad-leafed trees surround a clearing of packed earth. Halflings of all ages wearing only loincloths seem to be preparing a feast, fruits, nuts and fish. One male is pointing to something out of view with a pearl knife blade.
Screams cannibalistic halflings of Darksun to me. Either that of Hobbits of Middle Earth.
Door 4: A long scrubby hillside, sloping down. In the distance some deer (?) are drinking at a creek. For once there seems to be no structure around the door. The door opens about 6’ above the ground apparently hanging in mid-air.
The door is above the ground? Like the land has moved but the portal hasn't.
Actually appeals to the puzzle nature in me.
Door 5: A wall of sand appears to hang in mid-air, obscuring almost everything. In the middle distance you can see some shadowy forms. You get the sense that the sand is moving at tremendous speed.
Blowing high speed sand........
no thanks, I've sand blasted metals before and know what it could do to skin.
Door 6: A cramped wooden corridor, everything is slightly curved and damp looking. Barrels and sacks fill much of the space. Although the right side of the corridor has several Halflings chained together. One of the Halflings is holding up a free hand with a key in it, and is grinning.
This holds adventure in helping the halfings escape or preventing.
Door 7: An overgrown yard overlooking a wide track where several men stand among panicky a mule train. Some are fighting a two-headed creature, one head is canine the other feline. In the middle of the chaos a man looks at the sky. Tears run down his face.
Good lord its a mule and several of them, am I Epic levels? The gaezebo can't be very far from here.
The hero in me would rush forward to defend the mule train.
Door 8: A shadowy and twisted city – many of the structures are red clay, but here and there is a different structure, its architecture completely out of place. On the next street over you spot a building that might be the Blue Boar. A familiar inn frequented by students in the city of Dae Terrus. These streets are dark and deserted.
If I know an inn in a city, does the rest of the city look like it?
This doesn't really pull at me unless it's a shadow plane version of it.
Door 9: A dark hallway 10’wide, with softly glowing fungus on the walls, a broad staircase leads down, with a small band (at least 4) of dwarves coming up it. Three of the dwarves are heavily armed and armored, while all carry huge, overstuffed packs.
Dwarves aren't know for being to friendly on those who intrude on their tunnels uninvited. Might be a fight before you get a chance to say anything.
Door 10: Rough men dragging chained captives move between the houses in a small village. An older man stands in the center of a whirlwind, menaced by a bigger man holding a whip. The old man bears the symbol of Yanna, the goddess of Air, Freedom and Trade.
Appears as the old man is attempting the freeing of the slaves.
===========================
I would have to go with 7 or 10.
Leaning at 7 for the instant help factor.
10 says that the old man picked this fight on his own and could probably take care of himself.
