Despite illness on the part of the DM, this session happened! So yay.
The PCs continued on down the corridor, they... You know what? Instead of narrating what the PCs did, I'll just describe the things they found out. It's easier that way.
They found a city, called Refuge, populated by a people called the Blessed. The Blessed are made up of all different races, none of which breed true. Gnolls marry elves, kender marry dwarves, and the children produced are of every race under the sun - no half-gnoll-half-elf mixes. All these people live together in peace and harmony, most of their needs provided for by a substance called the Essence.
The story of Refuge is as follows: seven thousand years ago, something called the End of Ages happened. The folk wisdom is that the gods scoured the land for some sin, but who knows how true that is? The surface world was devastated, and people retreated underground. Some, like the dwarves, shadowpeople, and Hest elves already were underground. Some, like the goblins and kobolds already were often underground, and some, like the draconians retreated underground to survive. These races still all survive in their own cities in the Underdark of Krynn.
But other individuals of countless races were all drawn to one cavern. There, they found a town, all made for them. There were fortifications protecting the cavern from the outside world, waiting to be manned. There were buildings waiting to be occupied. There were fields ready to be plowed. And all of this was made of the Essence, a somewhat-translucent, blue substance that gives off a slight glow. The Essence is hard, but not brittle, burns cold, is edible (when in the form of vegetables), and seems to be in limitless supply; if a blacksmith needs more essence to make tools with, he can just go into the back room and get a block, and the pile never runs out. With the bounty of the essence, and the mingling of the races, a harmonious society was created.
A few centuries after the Founding, a man named the Traveler came to Refuge, and taught the Blessed many secrets, like how to plant crops more efficiently, and so forth. Before he left, he gave into the charge of the Blessed a book, to be given to an individual who met a certain description.
Eventually, Refuge grew to the point where the Essence couldn't keep up, and they started making houses and growing food out of mundane materials. So far, this hasn't caused any problems in society. This also explain's Refuge's need of trade, and continued contact with other cities in the Underdark.
The Blessed do not see the PCs as separate people. Rather, they see the PCs as one androgynous person of a race without any real distinguishing characteristics. When a PC picks up an item, this person picks up an item. When two PCs talk over each other, the person makes the noises of two voices at once. If the PCs are more active than one person can handle, other events start happening as if by magic. In fact, this person that the PCs are seen as being perfectly matches the description left by the Traveler, and they were given the book. The book contained a description of them, down to the names and races of the 'identities' this person purports to have.
The book was empty, but for the description and these five images:
The image of the course of someone's life. On the left, a baby crawls. Then an infant walks. By the time you reach the right side, there is an old man, leaning on a cane. Beneath the left side is the shepherd's crook and some flowers. Beneath the right side is a tongue of flame and some dead grass.
A great tree, a pile of ashes, a shepherd's crook etc., and a single tongue of flame, are all encircled by a black line. The whole image has a small golden halo drawn over it.
The silhouette of a humanoid figure. Inside the silhouette are contained a number of flowers and blades of dead grass.
An enormous treant stands next to a broken bowl of ashes. Some sort of flower spirit is standing next to the bowl, with ashes on its hands. The treant is drawing back its clawed hand to destroy the flower spirit.
A tree is bent over, almost as if in mourning, beside a tombstone with a picture of a pile of ashes on it. One of the tree's branches is holding an uprooted flower.
There is one more unusual feature of Refuge: the Wyvern in the Well. At the center of town, there is a deep well, some fifty yards across and two hundred yards deep, with a dry bottom. And at the bottom is an enormous wyvern. Any person can, once in their life, ask the wyvern a question – any question – and the wyvern will answer. The wyvern has never yet failed to answer a question, nor been wrong. In return, the wyvern asks of the questioner one thing.
So the PCs travel to the wyvern (uncertain whether they will get only one question, since there is, apparently, only one of them, or five, since they're pretty sure there are in fact, five of them) and ask it, "How do we get our memories back?" The wyvern replied, "Discover who you really are."
The wyvern then asked the asking PC its question: "Who are you?" The asking PC, of course, didn't know, and the wyvern killed the entire party. The wyvern did take some pity on them, though, and revealed that, of the five images in the book, three were categorizations, and two told the story of the End of Ages.
They ended the session having just woken up. Somewhere.
